The Basics

Drag a block with a number on top of another block with the same number to merge them into a block with a higher number. Some blocks will be connected and can only move together. New blocks will add from the bottom and push everything up, once the blocks reach the top the game is finished.

Difficulty

There is just one level, which does become increasingly more difficult as you have merged more higher numbers.

Variation

Lacks variation in this just one level game.

Visually

Graphics are simple, but functional.

Free vs Paid

Feature complete, but just too many ads. For example the ad for another game during startup and the ads during game play or just too much.

Is It Any Good?

I give Merge Blocks: Star Finders 7 out of 10 stars. Game itself is fun, but the ads make it hard to determine if this is worth spending on.
