About this game

One Ball Left is a clever ball puzzle game about sliding, hitting, and thinking ahead. Explore 1,000+ levels built around clever collisions and chain reactions.

The rule is simple: choose a ball, swipe in one direction, and hit another ball on the grid. The hit ball keeps rolling. If nothing blocks it, it leaves the board.

Your goal: clear the grid until only one ball remains.

Sounds easy? It is not. Every move changes the puzzle. A perfect hit can solve the level. A careless move can create a dead end. Read the board, plan the chain reaction, and choose the right ball at the right time.

WHY YOU WILL LIKE IT

• Simple swipe controls: tap a ball and swipe up, down, left, or right.
• Smart logic puzzles built around position, move order, and chain reactions.
• Chain-hit gameplay: one ball hits another, sending the next ball rolling.
• One clear goal: leave exactly one ball on the board.
• Increasing difficulty: face more balls, more complex layouts, and trickier solutions.
• Helpful hints: stuck on a level? Use a hint to find your next move.
• Dead-end detection: if the board can no longer be solved, the game lets you know.
• Quick to play, hard to master: enjoy a few puzzles during a short break.

HOW TO PLAY
