Merge Master Blue Monster is a free-to-play puzzle game where you'll need to evolve your monsters by merging them. The more monsters you have, the more challenging and fun your gameplay will be!
To get started, you need to choose one of the available monsters to merge. When you're ready, simply tap on the screen to begin merging monsters.
The gameplay is easy to understand but still quite difficult to master. The difficulty increases with each level, so be careful and complete the task to unlock all monsters.
