Bitcoin.io

Bitcoin.io drops you into a competitive arena where the goal is straightforward — absorb everything smaller than you and avoid everything that isn't. You start as a tiny coin navigating a field packed with glowing pickups and other players doing exactly what you're doing.

Growing larger feels rewarding, but size comes with trade-offs. Bigger players move slower, which makes escaping a tight situation genuinely tense. The gap between a good run and a sudden elimination can close in seconds.

The crypto skin theme gives the whole thing a distinct visual identity without getting in the way of the gameplay. Rounds are short enough to replay immediately, and the leaderboard shifts constantly, so no position ever feels secure for long.
