Give the wheel a spin.
Roulette, as the app deals it: the pocket is drawn first, evenly from all 37, and the ball is only there to show you. Nothing is staked.
Flick the wheel, or press Spin

Every bet pays 37 ÷ pockets covered × 0.95, so each one returns 95% over the long run.
01The cut
You set the odds.
Real casinos keep a slice of every bet and never tell you how big it is. Here it’s a slider, and every game shows you exactly what it’s running at. The app ships on Vegas Floor, 5%, roughly what the wheel and the reels take in a real casino.
Preset
5% edge, roughly a Vegas floor: the wheel, the reels and the side bets. This is what the app ships on.

Picking a preset clears bias and always-win/lose, so the game is clean and verifiable. Blackjack and Dragon Tiger have no edge slider, so a preset sets their rules instead: the blackjack payout and what a tie does. Dice is the other exception: its payouts are locked fair, and rigging it moves the roll.
02Games
Eleven games, and each one prints its odds.
Every payout table is derived from the fair table and scaled by the edge you chose, so the maths is the same shape in all of them. Poker is the one table with no house: it’s you against four bots.
Crash
Cash out before it busts.
Multiplier climbs; cash out before it dies. Instant-bust chance, max multiplier, and climb speed are tunable. Speed is cosmetic.
The maths
Cash out at any target t: win chance (1 − edge) / t, pays t. Expected return is 1 − edge for every target. No cash-out strategy beats another.
Blackjack
Beat the dealer to 21.
Six-deck shoe by default. Hit, stand, double, split. Blackjack payout (3:2, 6:5 and more), dealer on soft 17, and deck count are tunable.
The maths
No edge slider: return falls out of the rules. The quoted RTP is what perfect basic strategy returns for this table; the simulator plays the same strategy against the same shoe.
Poker
Texas Hold’em. Play the table.
No-Limit Hold’em at a five-seat table: you and four bots, 5/10 blinds, 500-chip stacks. Fold, check, call or raise.
The maths
No house and no odds dial. The table plays for its own chips, kept apart from your bankroll, and the bots run on a simple hand-strength heuristic, not a solver.
Mines
Pick gems, dodge mines.
5×5 grid. Default 3 mines (1–24). Sequential picks; cash out or bust.
The maths
Paid multiplier = (1 − edge) × fair. Survival × multiplier = 1 − edge at every rung.
Roulette
Red, black, or the number itself.
Single-zero European wheel, 37 pockets. Straights, splits, streets, corners, six lines, dozens, columns and every even-money bet.
The maths
Every bet pays 37 ÷ pockets covered, scaled by 1 − edge. A straight number and red/black return exactly the same over the long run.
Pinball
Drop the ball, take the bucket.
Plinko-style peg field. Default 12 rows. Risk Low / Medium / High reshapes the bucket table.
The maths
Table is derived from the binomial board, then scaled to 1 − edge. Risk only changes which buckets pay, not the long-run return.
Chicken
Cross the road. Don’t get flattened.
Cross lane by lane and cash out whenever. Four roads, from Easy (one truck in twenty-five) to Daredevil (fourteen in twenty).
The maths
Each lane pays the reciprocal of the chance of reaching it, scaled by 1 − edge. Stop on lane one or walk the whole road: same return. The multiplier climbs because the odds get worse.
Dice
Call it over or under.
Roll 0.00–100.00. Set target and over/under. Multiplier, target, and win chance are three views of one number. Win chance capped at 98% so payout stays above 1×.
The maths
Payouts are fair (edge locked at 0). Rigging is via roll bias, which does not change the printed multiplier.
Slots
Three reels, one payline.
Mechanical three-reel strip (22 stops). Faces: Clover, Diamond, Heart, Bell, BAR, Seven. Volatility Low / Medium / High.
The maths
Paytable is generated from the strip and scaled to 1 − edge. Volatility only changes how top-heavy the table is.
Dragon Tiger
Two reels, one card each. High card wins.
One card to Dragon, one to Tiger; aces low, kings high. Tie and Suited Tie side bets, on a two- to eight-deck shoe.
The maths
No edge slider: the house lives on the tie. Whether a tie loses all, loses half, pushes or wins half on the main bets sets the return, and the app prints the exact figure.
Loot Boxes
Open a box. Pray for the watch.
Four boxes: Luxury, Tech, Streetwear and Garage. Every item holds a fixed number of tickets; opening a box draws one.
The maths
Each item pays its value over the box’s average drop, scaled by 1 − edge. The price spread only decides how rarely the money comes back. Rarity is read off value, never typed in.

03Training
Learn the table while you play it.
Blackjack, Poker and Dragon Tiger can coach you through every hand: what’s happening, what your options are, and what a good player would do. The coach follows the hand you are actually playing, not a scripted tutorial.
Two switches
Turn training on during setup or in Settings, then start the coach from the Training button at each table. Once you know a game, switch that table off and leave the others on.
The advice the games already use
Basic strategy for Blackjack. Hand strength against pot odds for Poker. For Dragon Tiger, why the tie bet costs more than it looks. A guide, not a solver.
It shows you the odds
The coach quotes the table’s own numbers, like how often the dealer’s hole card is a ten, so you see what each choice is worth.
Blackjack
Training onBlackjack pays 3 to 2
Dealer · 10
Training
16 against the dealer’s 10
Any card worth more than 5 busts you. Hit takes another card. Stand keeps your total and ends your turn.
Basic strategy: Hit. The dealer’s 10 will often finish on 17 or more, and 16 won’t win standing. Take the risk.
04The levers
Including the dishonest ones.
Every game can be forced to always win or always lose, a teaching switch, or all of them at once with the Win Everything and Lose Everything presets. Most games also carry a bias dial that quietly moves the real return away from the printed table. And a script can line up the next rounds in order: four losses, then the one that pays for them. That is exactly the trick worth understanding, so it is in the app rather than hidden from it.
Dice
Always win
Every round pays. A teaching switch.
Always lose
Every round busts.
Moves the roll. The printed multiplier stays exactly where it is.
Scripted rounds
What the lobby shows
Dice
Call it over or under.
Clean. What the table prints is what it pays over the long run.
Whether a lever is set is never hidden: the badge shows in the lobby. Pick any odds preset and both the bias and the always-win/lose switches clear.
05Prove it
Run a million rounds and check.
Settings has an RTP simulator. It runs your live configuration (the edge you set, the bias if you set one) and reports what actually came back against what the table promised. The one below is real too: pick a run size and it plays it, here, in this page.

This is local simulation, not a blockchain claim. The odds are yours to set, the code runs on your phone, and the simulator is there so you do not have to take the table’s word for it.
06Looks
Three themes. One set of odds.
A theme is cosmetic. It changes the lobby, settings and the games, never the odds.
Minimal
True black, near-white, one hairline. The default, and what this site is built from.
Arcade
Navy boards with labelled axes.
Royale
Felt green and gold, like the table it’s imitating.
07Local
Nothing leaves the phone.
No game server
Every round is generated on your phone. There is no backend holding your balance, and nothing you play is uploaded. The only network traffic is Apple’s, when you buy or restore something.
No accounts
No sign-in, no email, no profile. Purchases are tied to your Apple Account by Apple, not to an account with us.
Nothing pays out
Credits are invented, including the ones you can buy. Nothing in the app can be won as money, withdrawn, cashed out, or transferred, and none of it has value anywhere.
On-device storage
Balance, history and settings live on your phone. A small copy of the bankroll is kept in the device keychain, so reinstalling brings back the same balance rather than a fresh stake.
The rest of it
Lobby
Balance hero, rounds, wagered and realised RTP. Star a game to pin it.
Bankroll
300 credits to start, handed out once. There is no free reset: a bankroll running down is the thing the app is showing you.
History and stats
Every settled round, kept on the device, with realised RTP per game and your worst fall.
Saved houses
Save a tuned set of odds under a name and switch between them.
Currency mark
The chip icon by default, or a custom image, or a typed symbol up to three characters. Display-only.
Autobet
On every game except Poker. Useful for watching a house edge do its work.
Languages
English, French, German, Italian and Spanish, or follow the device.
Haptics
On or off. Cosmetic, like the themes.
08About
None of this is real. That’s the point.
LarpCasino is a simulator. No real money is wagered in this app. Credits cannot be won as money, cashed out, or transferred. Everything is generated on your device and stays there. The odds are yours to set, which is the point: it exists to show how the maths behind these games actually works.
Rated 18+ for simulated gambling. This is not gambling for money: there are no deposits, no withdrawals, no wagers of real currency and no prizes of any kind. Anything bought in the app is an ordinary App Store purchase, not a stake. Credits are invented and have no value inside or outside the app, whether they were bought or not.
On first launch the app walks through six steps: the disclaimer, the odds, a theme, a currency mark, training, and then you are ready. The disclaimer is the first thing it says, and it says: none of this is real.
