About us

Last updated: October 29, 2026

Otto Spins is a free-to-play social casino for adults 21 and over in the United States. It has 44 original games, from classic slots to blackjack, baccarat and roulette and quick rounds like Peg Drop and Tower Climb. Every game runs on virtual coins that cost nothing and are worth nothing outside the games.

How the coins work

Every new account starts with 10,000 coins. On top of that you get a coin bonus every four hours, a seven-day login streak, level rewards for the rounds you play and a free top-up whenever your balance runs low. Coins cannot be bought, sold, transferred or exchanged for money or prizes. There is no shop and nothing to deposit.

How the games work

Every game was made for Otto Spins and runs in your browser without a download. Results are random, and each game page shows its average return. The games are entertainment: success at Otto Spins does not mean success at real money gambling, and we do not advertise or link to gambling sites.

Playing responsibly

Our Responsible Play page has a time reminder, a play break from 24 hours to 30 days and free, confidential help lines in the United States.
