## What is One Ball Left?

One Ball Left is a clever ball puzzle game about sliding, hitting, and thinking ahead.

One Ball Left has 1000+ Levels!

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. To win, you need to 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, swipe up, down, left, or right, and watch the collision unfold.

• Smart logic puzzles
This is not just a sliding game. Each level is a small brain challenge built around position, timing, and chain reactions.

• Chain-hit gameplay
One ball can push another, and that ball can keep rolling. Think ahead before you move.

• One clear goal
Remove balls from the grid and leave exactly one ball behind.

• Increasing difficulty
Start with easy boards, then face harder puzzles with more balls, tighter limits, 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
Perfect for short breaks, daily brain training, and anyone who enjoys clean puzzle games.

HOW TO PLAY

1. Tap a ball to select it.
2. Swipe up, down, left, or right.
3. The selected ball must hit another ball in that direction.
4. The hit ball continues rolling.
5. Balls with no blocker ahead leave the grid.
6. Win by leaving one ball on the board.

If you enjoy logic puzzles, ball puzzles, sliding puzzles, grid puzzles, brain games, or chain reaction puzzles, One Ball Left gives you a fresh challenge in every level.

Can you solve the grid and leave just one ball?
