Fifteen - Flip tiles, find gems, dodge mines

fifteen is a quick tile game that lives in your toolbar. Every round takes about a minute, so it fits into a coffee break, a slow build, or the wait while an AI agent works. How it works - Pick a bet and how many mines hide on a 5×5 board. - Every gem you flip grows the pot. More mines make it grow faster. - Bank whenever you like, or keep going. Flip a mine and the bet is gone. Play with friends - Add friends by username and see who's online. - 1v1: you both play the same 3 boards. Highest score wins, with an optional wager. - Send a challenge code so a friend plays the exact board you just played. - Make a group with its own leaderboard. Built-in Pomodoro - Set a focus timer and how many rounds a break gets. - fifteen tells you when your break is over, so a quick game never turns into an hour. Something new every day - The daily: 3 boards, the same for everyone, free to play once a day. Share your result. - 3 daily missions that pay out. - A weekly season with winners, losers and medals for the top 3. Also - Put money in the bank to keep it safe for a bad run. - Power-ups: a shield that survives one mine, a peek at nearby mines, and a golden tile that doubles the pot. - A full shop: gems, mine styles, boards, tile shapes, name colours, titles, bank effects and sound packs. - Works offline with practice money. The money in fifteen is pretend. It can't be bought, sold or cashed out.
