About

Thia's Roulette

Features
Read full description

Thia's Roulette brings the real casino wheel to your pocket — European and American, solo or at a live table with friends. No purchases. No real money. Just the spin. TWO WHEELS, YOUR CHOICE Play the European wheel (37 pockets, single zero) or the American wheel (38 pockets, with both 0 and 00). Every standard bet is on the board — Straight Up, Split, Street, Corner, Six Line, Red/Black, Odd/Even, High/Low, Dozens, and Columns — all at standard house-edge-neutral payouts, just like a real table. PLAY SOLO OR AT A LIVE TABLE In Single Player, spin against the house at your own pace, with every result generated by your device's secure random number generator. In Online Multiplayer, join a public table matched automatically, or create a private table and share the room code with friends — up to 6 seats per table. Every seated player contributes to the spin through a commit-reveal scheme, so no one — including whoever's hosting — can influence the outcome. Connection drop mid-round? Your seat holds for a short grace period so you can rejoin without losing your place. CHIPS, WITHOUT THE WALLET There's no in-app purchase for chips, ever. Collect a daily login bonus, and top up any time by choosing to watch a rewarded video ad — including automatically if your balance ever hits zero, so you're never stuck on the sidelines. NO ACCOUNTS, NO PASSWORDS Thia's Roulette is guest-only — no sign-up, no email, no password. Online multiplayer runs on your Apple Game Center identity, and your chip balance and game history travel with your Apple ID via Game Center and iCloud, carrying over automatically across your devices. BUILT LIKE A REAL TABLE A hand-finished wood-and-brass wheel, a felt table, and a ball that actually spins to rest on your number — not a slot-style random flash. Full game history, adjustable sound, and daily bonus reminders live in Settings. FREE, SUPPORTED BY ADS The game is funded by occasional interstitials between rounds and rewarded videos you choose to watch — not by purchases or a subscription. Thia's Roulette is a game of simulated chance intended for entertainment purposes only. It does not offer real money gambling, and success within the game does not imply future success at real-money gambling. Chips have no real-world value, cannot be purchased with real money, and cannot be redeemed or exchanged for money, goods, or prizes of any kind. Intended for a mature audience (17+).
