Merge Defense: Pixel Blocks is a casual merge and tower defense game that blends simple puzzle mechanics with strategic grid placement. You merge two blocks with the same number to create a higher value block. Place merged blocks on your fort grid to attack incoming invaders automatically. Higher numbered blocks deal more damage and last longer on the field.
The core loop is easy to learn and hard to master. You manage limited grid slots, decide which blocks to merge, and plan placement to maximize damage and combos. Enemies come in waves with rising difficulty, so you must combine quick merges and careful positioning to hold your fort. The game rewards chain merges and timing, and includes power ups and temporary boosts to help clear tough waves. Play online for short sessions or extended runs and aim for high scores and efficient merges.
