The Game Room


Now then, with the smithy’s construction started, we also pushed forward our preparations, finishing the game room.

Though I call it that, it had slots, dice, and other things I put in the dungeon chests a few days ago. Furthermore, the inn even started buying the playing cards for five coppers.
… The tables were prepared with cloth coverings for the dice and playing cards, just a bare minimum to be acceptable rentals. We also let people bring in their own dice and cards.

If someone asked why it took so long even though that’s all there was, I also soundproofed the walls so that it wouldn’t obstruct the guests’ (and my) sleep, adjusted the slots, and developed dice golems for some trickery business. Well, let’s take a look at them one by one.

Soundproof walls are obvious. For now I just put some sponge that I bought with DP inside the walls and that seems to have done it one way or another. Although it feels like the walls’ thickness increased a bit, they’re still within acceptable levels.

Adjusting the slots in various ways, I made them rarely be big wins and lose sufficiently. Naturally, it’s at the point that the owner wins when looking at the whole.

For the dice golems, they’re insurance for when I use them. When you fill them with magical power, you can make their center of gravity be biased for just ten seconds. After ten seconds, they’re ordinary dice.
Their material is transparent crystal. Since they’re filled with oil that has the same refractive index, you can’t see their internal structure at all. Getting that right gave me a really hard time.
If people could see it and found out, they’d say something like, “Isn’t this fraud?” Well, it really is though. There’s a famous saying that it isn’t fraud if the fraud isn’t exposed.
Moreover, they use individual identification through magical power so that other people can’t use them. Golems can distinguish between magical powers. That mechanism can’t be used for dungeon keys or anything though.

With all that, I added on the game room. Stealthily, in the dead of night. Since I wasn’t able to sleep through the night and added on to the inn it can’t be helped that I’m lacking sleep. I’ve only slept nine hours today.

“I’ve been wondering for a while now, but how much sleep per day would satisfy Kehma?”
“I wonder… I guess twenty-five hours would be best.”

Still, the world also only had twenty-four hours in a day.

“… Can you use space-time-type magic?”

Woah, space-time-type magic reigns supreme. Should I look into it? I’d never have enough DP for it though.
Then, setting aside that farce, I unveiled the game room.

Our inn’s frequent guest, Gozoh, arrived immediately. He’s the first guest to commemorate its opening.

“… Was this here yesterday?”
“Ah, an A-Rank adventurer’s mage acquaintance made it overnight.”
“Hooh… It would’ve been great if he took the chance to make Kantra’s smithy too while he was at it.”
“The commission fee is pretty high. It’s better to make it normally.”

Moreover, the construction had already started, it’s better to not deprive Carpenter-san of his job.
Moreover, I don’t want to do any extra work. I don’t want to work. I don’t wanna work!

“Oi Kehma, what’s this? A room to chat in?”
“No, it’s a game room. You play dice and cards at those tables. Well, this box is—”
“And sloooooots!”

Ichika ran past me in the middle of my explanation.
Incidentally, I raised Ichika and Meat’s wages. It’s something more like pocket money though.
I give them money that’s simple to understand, and if they want something I’d buy it with DP. Ichika’s basis of food is disappearing. No, it disappeared.
As for why that’s past tense, recently Ichika has been waiting for the game room to open, saving up for her slots campaign fund.

“Hyahha—! Put three copper in! Next, lower the lever! Spin, spin spin—! Ahahahaha! Button, button, push the button! Stop! Tch, one more tiiime~!”



Her eyes are scary. Fanatical even.
Yep, ban the slots… is it already too late?”

“H-hey, Kehma? That, is it safe? It’s not a dangerous box?”
“… It’s a slot machine, for gambling.”

Ichika was pulling the slot machine’s lever with all she had, totally addicted. Aren’t guests supposed to be doing that?
… Well, I’ll let it be.

“… Changing topics, do you play cards? There aren’t any cards, I’ll play with you.”
“Hmm? These have been appearing in the dungeon recently. I heard you’d been buying them, but they were for this huh? Please teach me the rules.

I taught Gozoh how to play poker and blackjack.
Because the rules were easy to get, it seemed he liked blackjack.

“If there were enough people we could play old maid or sevens too.” [1]
“There’s a lot of ways to play with them huh, these card things. You thought up so many ways to play even though it’s only been a few days since they started appearing.”
“Well, I just obtained a book that showed ways to play. I got it in the dungeon.”
“I see, so that’s why you started buying them then.”

Furthermore, they’re one silver if someone wants to buy them. The overcharging is because there still aren’t many of them.
It’s a pretty good harvest considering that it only costs 5 DP for adventurers to get them. I’ll be buying them for twenty-five copper eventually, so maybe the final sale price will be around fifty copper?

“Well then, next is dice bu—”
“It’s here! YES YES yeeesss! Grand prize! Grand priiize!”

When Ichika shouted out, the jingling sound of copper coins overflowing from the slot machine could be heard… Yeah, I should prepare a box.

“Ooh!? That’s amazing!”
“Fufufu… With this I can keep playin’…!”

The slot machine’s already spinning though.

“Hey, let’s give this a bit of a shot. Kehma, how do you use it?”
“It’s explained on the label here. Well, it’s not that hard. It gives a return depending on the pattern.”
“Indeed, I see it here. But with an adventurer’s eyes, something at this level is very very simple, mu—gu? T-this is surprisingly difficult…” [2]

Sorry. It’s all luck.




After a while, other inn guests showed up as well. Though I say that, there’re only five parties staying here including the merchants, but all of them gathered.

“Even though that table there is for dice, it has cloth on it eh? Oooi, Doran, got any dice? I’ll be the dealer first, let’s go with hi-lo! [3]

“Do it! Going in turns of being dealer twice should be fine. Anyone else want to join?”

“Heeeh, those cards were things to play with huh… Maybe I should get some cards of my own too? Next time I’ll not sell them if I find any.”

“Hohoh, I’d also like to buy a house here…”

“Gikkon-san, let’s play this [Sevens] game!”

“Sure, why not? Does Roppu-san want to join in with us?”

“Nn, let’s mix up a bit. My partner’s been playing with that box for a while now.”

“Oh, Gozoh-san? What’s that?”

“It’s a slot machine! … Oooh, I won!”

A noisy crowd of people. It was exactly that kind of a feeling. The room is considerably roomy since I made it large thinking about the future, but it’s crowded. Feels great. [4]

“Ugugugu, my slot machine…”

And so, Ichika, who’d tried to monopolize the slot machine despite being an employee, was now taking a break.
Even though she hit the grand prize, she finished at a plus-minus of zero when all was said and done. People are surrounding it now too. At any rate, it doesn’t look like it’ll open up any time soon. It wouldn’t be good for an employee to occupy it when it’s crowded like that.

“… The slot machine looks popular huh. Maybe I should make another?”
“Goshujin-sama! Then definitely, a slot machine for my personal use…!”

Yup, Ichika’s recovered a bit of her true character hasn’t she?

  1. He should just make her one and have it run on rocks or something. After all, its the thrill she’s after, not the money. Though, there not being in real risk involved might kill it for her.

    How many slot machines did he build? If it wasn’t at least as many as he has rooms for rent, it wasn’t nearly enough. Slots are always one of the most important gambling devices in a casino. One of the most popular too I believe.

    1. I think I may have put multiples in previous chapters, since the raw didn’t indicate exact amount (only imply)…

      He only built one.

        1. She was using one until the guests took it from her… I think?

          Dunno. Again, it never actually says how many. Any plurals/singulars I use are just assumptions.

          JP is hurd.

          1. Well, its probably not important in the long run. However many he made, it wasn’t enough. Honestly, if non-inn guests are allowed in, then I don’t think its possible for him to make enough without drastically expanding the size of that room.

        1. What do you mean Keima has already custom built them for fraud he can’t make them anymore fraudulent without making it a blatantly obvious scam lol.

          1. I meant from the customers. Obviously not worried about the fraud from the MC. Though I do wonder who he’s going to have running the game room. Ichika can’t be trusted to run something like that, Meat’s got important hug pillow duties and the others can’t do math.

    1. The whole inn seems to good to be true, it was mysteriously built in one night, and seems to expand about the same time as Keima decides it needs to be bigger…

    2. Remember kids, always Save after every big win… and winning streaks too! And if you lose too much there’s no shame in loading!

      Got it? NO SHAME!

      NO SHAME! NO SHAME!!! … ………… ….. my ears are beginning to turn red again…😖I should really stop shouting like a kid…

  2. Thanks for the chapter! Keima probably won’t realize how much soundproofing he needs once his casino gets going. I wonder who will be the bouncers.

    1. BTW, in case readers don’t quite understand the slot machine he built, Japan has a variety of slots that normally run on something similar to a token. It looks and acts like a Vegas style slot for most of its behavior with one major difference. While Vegas slots just spin on their own and stop when they are designed to, the machines in Japan have a set of buttons on the front that, when pushed, will stop the drum from spinning. You don’t just pull the arm and wait for it to stop whereever it feels like, you can actually try and stop the drum on the prize you want. The Drums are fairly good sized though and are spinning quickly so it can be hard to hit the button at exactly the right timing.

      An example of a Japanese slot machine:

      The 3 red buttons in the middle stop the drums from spinning when they are pressed. Apparently they are called Pachislo there.

      1. Most slot machines actually have the option to push the buttons individually from the front if you so choose IIRC. people just like pulling the handle in north america.

        1. Wrong kind of buttons.

          Those red buttons don’t start the drums spinning, they STOP the drums from spinning. I have seen the slots in Vegas and other gambling spots in the US and the buttons they have control the amount of bet, place the bet, then start the drums spinning. Once the drums are spinning you just watch them passively until they stop and see if you won anything. With the Japanese ones the drums will spin until you put the button to stop it, or a set amount of time passes. Each of the red buttons stops the corrosponding drum, the left red button stops the spinning of the left drum, etc. There are actually magazines that show the layout on each of the drums for a particular machine and try to give hints and tips about the timing for stopping each of the drums.

          Here is a pic of another example:

          The red button on the top of the flat area is the MAXBET button that you are thinking of to start the drums on their way. If you look below that you will see the 3 buttons used to stop each of the drums.

        2. Hunted around a little and actually found a YouTube video on how to play the Pachislot or Okislot. (Not sure if the names are interchangeable)

          I wonder if that will imbed the video in the post or just be the link.

          If the links get too anoying feel free to mess with them Ziru, its another cultural thing that many will not know about but if the links are intrusive or bothersome feel free to edit the posts.

  3. and this is how it goes now in that Inn…
    1. Go to Dungeon to kill/harvest stuff
    2. Sell harvested stuff in Branch Guild/Merchants
    3. Go to Inn’s Game Room
    4. Rinse and Repeat~~~

  4. These people are all idiots if they keep accepting that “A rank mage in the middle of the night”. Who travels in the middle of the night just to build something and then leave?!
    Thanks for the chapter! 😀

    1. Who says they have left? Keima could just say they are staying in the A rank room and doesn’t want to come out. Also as an A rank they wouldn’t care bout time of day and instead if they prefer being mysterious they would travel at night to avoid people which is the story Keima could use.

    2. It’s the acquaintance of an A-rank, plus, they are probably showing up on their free time after working hours, as a favor to Haku-san. Just get off work, teleport to the inn, cast construction magic, port back home and sleep.

  5. I don’t get the point of the fraud here. He’s putting a lot of effort into something when casino games are already naturally stacked in his favor.

    1. His schedule is much too busy as it is, for him to devote time creating and maintaining fair gambling machines. What more can people ask for, he’s already had to cut back his sleeping to only 9 hours?

      1. I was thinking it would take him less time though. Getting things in the favor of the house isn’t difficult, you just need to make sure the pay out is less than the odds of winning. If we had, say, a coin flipping game where I’d pay you any time it landed heads, I’d charge you a dollar per flip and give you $0.90 for any time you won. No need to design a super coin which would only land heads when I allow it to.

        1. You got your numbers wrong, just saying.

          Nobody would want to play a game where the prize is definitely lower than the cost to play.
          It should be the expected returns of the game over a longer period of time would be $0.90.
          So in your case, given that it is a fair coin, you would win $1.80 on heads, nothing on tails. Since heads is expected 50% of the time, the long term returns would only be $0.90.

          1. I was thinking you’d get $1.90 on heads, but yeah, I realized I worded it poorly after posting.

  6. Thank you kindly for the chapter.

    Poor Kehma, never getting enough sleep ever again. ^w^

  7. LOL I love it! The amount of shady self working is great. All he needs now is a few “workers” to be dealers and summon a bouncer or two and he’s golden. Free money and DP! I wonder what he’s going to add next~ If he starts making housing now he can start on the can’t destroy the dungeon plan. Ah that moment where the poor guy only get’s 9 hours of sleep… LOL

  8. I wonder if he will ever think to put the dungeon core under the floorboards of his room in the inn? No adventurer would ever look for it there.

        1. Its the size of a basketball, that would be a big fish tank. I wonder if he could have used dummy cores for lighting in part of the inn as a way to hide them, would be expensive in DP though, given the price of each one. Unfortunately they are a little large to hide easily without being clever on how you go about it.

            1. Cut out a section of the floor so it’s not sealed. Cover the hole with a throw rug. Put a table on top of the rug so nobody steps in the hole.

              Assuming Keima ever lets anyone into his room to begin with…

          1. lol make it something similar to a chandelier, no one would think it’s a dungeon core XD, and if they ask, could just say it’s modeled after it, since they’re near a dungeon.

  9. Thank u always for ur great work…

    ” it can’t be helped that I’m lacking sleep. I’ve only slept nine hours today. ”
    Pffff, ahaha, ahahahahaha…

    ” Her eyes are scary. Fanatical. ”
    We got hardcore one in here!!!

    This chap really rock my stomach…

  10. Random correction:

    ” copper coins overflowing from the slot machine could be heart”

    ” copper coins overflowing from the slot machine could be heard”

    1. Grumble, should have gone over all of it before posting that.

      “After a while, other hotel guests came arrived as well”
      “After a while, other hotel guests arrived as well”

      came or arrived, no need for both.
