# Casino & mini-games > Eight casino games on Discord with published odds: coinflip, slots, crash, mines, blackjack, roulette, dice and hilo. Free, played with server coins. Canonical: https://ganyu.fr/en/wiki/casino Last updated: 2026-09-06 Bet your Ganyu Coins on eight games with fixed, transparent odds. All bets are integers, between 10 and 1,000,000 coins per game (up to 2,000,000 at coinflip for premium players). ## Coinflip Each flip is won at 50%. You pick a target streak (streak, from 1 to 10, up to 12 in premium): the payout follows 2^streak and the odds of reaching it follow 0.5^streak. A single failure in the streak and the bet is lost. The multiplier exactly offsets the probability: aiming for 3 in a row pays ×8 with a 1-in-8 chance. It's the fairest game in the casino. - `/coinflip [streak]`: Heads or tails in streak mode: aim for a run of N wins in a row. Target streak | Multiplier | Probability 1 | ×2 | 50% 3 | ×8 | 12.5% 5 | ×32 | 3.1% 10 | ×1024 | ≈ 0.1% ## Slot machine The bet is split across the three lines of the grid. On a line, three matching symbols trigger that symbol's multiplier; two matching symbols pay ×1.5 of the line bet. - `/slots `: 3×3 grid, payouts based on the symbols aligned on each line. Symbol | Three aligned 🍒 | ×3 🍋 | ×4 🍊 | ×5 🍉 | ×6 🔔 | ×10 ⭐ | ×15 💎 | ×25 7️⃣ | ×50 ## Crash The multiplier follows an exponential curve and can explode at any moment. The house edge is 3% and the payout is capped at ×100. The longer you wait, the more likely the crash. - `/crash `: The multiplier climbs continuously, so cash out before it explodes. Time elapsed | Multiplier ≈ 10 s | ×1.82 ≈ 20 s | ×3.32 ≈ 30 s | ×6.05 ≈ 76 s | ×100 (cap) ## Mines The grid has 24 tiles. You choose the number of hidden mines (from 1 to 23): the more there are, the more each safe tile revealed boosts the multiplier. Hit a mine and the bet is lost. The house edge is 3%. You can cash out at any time after at least one safe tile. The further you push your luck, the more the potential payout and the risk grow. - `/mines `: Reveal safe tiles on a grid of 24, cash out before hitting a mine. ## Blackjack Full blackjack played with buttons against the dealer: get close to 21 without going over. Hit, stand, double and split are available when the rules allow. A natural blackjack (21 in two cards) pays 3:2. A game left inactive expires automatically. - `/blackjack `: Against the dealer: hit, stand, double or split, with buttons. ## Roulette Single-zero roulette (37 slots, from 0 to 36), which gives a house edge of 1/37 ≈ 2.7%. The interactive panel lets you place up to 12 bets on a single spin before releasing the ball. - `/roulette [type] [number]`: European roulette (0-36): color, parity, half, dozen, column or straight-up number. Bet | Coverage | Payout Red / Black | 18/37 | ×2 Even / Odd | 18/37 | ×2 Low (1-18) / High (19-36) | 18/37 | ×2 Dozen (1st/2nd/3rd) | 12/37 | ×3 Column (1st/2nd/3rd) | 12/37 | ×3 Straight-up number (0-36) | 1/37 | ×36 ## Dice Choose a target between 10 and 90 and a direction (over / under). Your win probability follows directly from the target, and the multiplier equals 0.95 / probability, a 5% house edge. A riskier target pays more. - `/dice `: Bet that the roll (1-100) will be above (over) or below (under) a target. ## HiLo Each round, guess whether the next card will be higher or lower. The cumulative multiplier climbs with each correct answer (up to 10 rounds), with a 4% house edge. Cash out whenever you want… or risk it all on the next round. - `/hilo `: Will the next card be higher or lower? Up to 10 rounds chained together. ## Fairness and house edge Draws are purely random and identical for everyone: no result is adjusted based on the player, their bet or their history. Inactive games (crash, mines, blackjack, hilo, roulette) expire automatically after a few minutes. Game | House edge Coinflip | 0% (fair) Roulette | ≈ 2.7% Crash | 3% Mines | 3% HiLo | 4% Dice | 5% Blackjack | standard rules (blackjack pays 3:2) Tip: Over time, the house edge means the casino is not a get-rich strategy. /daily, quests and levels are. ## Frequently asked questions ### What are the minimum and maximum bets? Minimum **10** coins, maximum **1,000,000** per game across all games. Premium players can bet up to **2,000,000** at coinflip. ### Are the games rigged? No. The odds are fixed and public (50% per flip at coinflip, a 3% house edge at crash and mines, 4% at hilo, 5% at dice, ≈ 2.7% at roulette) and identical for every player. ### Which game is the most profitable? Coinflip is the only game with no house edge (0%), so statistically the "fairest". But no game wins over time: play for fun, not for riches. ### What happens if I leave a game in progress? Multi-step games (crash, mines, blackjack, hilo, roulette) expire automatically after a few minutes of inactivity and are settled according to the rules of the game. ### Which casino games does Ganyu offer? Eight: coinflip, slots, crash, mines, blackjack, roulette, dice and HiLo. All are played in Ganyu Coins, with fixed odds published on this page. ### Which game pays back the most over time? Coinflip, the only game with no house edge. Then come roulette (about 2.7%), crash and mines (3%), HiLo (4%) and dice (5%). ### How does crash work? The multiplier climbs an exponential curve and can blow up at any moment: you cash out before, or you lose the bet. The house edge is 3% and the payout caps at ×100, reached around 76 seconds. ### How does the Mines game work? The grid holds 24 tiles and you choose to hide 1 to 23 mines in it. Every safe tile revealed raises the multiplier, faster when there are many mines. You can cash out whenever you like after a first safe tile. ### Is the roulette European or American? European, single zero: 37 pockets from 0 to 36, which is a house edge of about 2.7%. The interactive panel accepts up to 12 bets on the same spin. ### Does blackjack allow doubling and splitting? Yes, hit, stand, double and split are offered as buttons whenever the rules allow. A natural blackjack pays 3:2. ### Can I restrict the casino on my server? Yes, through the Command rules tab of the [[dashboard]]: every game command can be switched off, or reserved for certain channels and certain roles. ## Sources and official documentation - [Discord Developer Docs: Message components](https://discord.com/developers/docs/interactions/message-components) - [Discord Community Guidelines](https://discord.com/guidelines) ## Related - [The Ganyu wiki](https://ganyu.fr/en/wiki.md) - [Economy & Ganyu Coins](https://ganyu.fr/en/wiki/economie.md) - [Fishing](https://ganyu.fr/en/wiki/peche.md) - [Levels & XP](https://ganyu.fr/en/wiki/niveaux.md) - [Raffle & collection](https://ganyu.fr/en/wiki/tombola.md) - [Fun commands](https://ganyu.fr/en/wiki/fun.md) - [Ganyu Arcade: poker in Discord](https://ganyu.fr/en/wiki/arcade-poker.md)
