Merge Balls is a funny game about merging the same balls so that you may get higher-level balls. The game play is not complex but if you leave the balls to fall carelessly the playing area will soon be congested. You have to find ways to mix balls intelligently to collect points and continue playing as long as feasible.

In the game you drop balls into the playing area and try to get balls of the same kind to touch each other. When properly united, they produce a new ball with larger size or better value. Keep combining to make a chain of combinations and rack up your score.
You have to keep track of where the ball is when you drop it. If you solely target the open space in front of you, the balls can be scattered and tough to combine. Try to move the similar balls closer, so you can merge them in the future turns.
Drop with intent: Think about where the ball will land and what other balls it can mix with.
Cluster: instead of spreading balls of the same type, put them closer together
Don't pack the playing area: Always leave space to facilitate handling in later turns.
Use merging chains: A single well-placed merge can initiate a chain of several merges in a row.
When you’re in a tight spot, stay calm: Scan the whole board and make plays that open up space.
Merge Balls is good for casual play for short periods. The more you play, the more you have to calculate your position to produce high level balls and break your own score records.
