Triadic

Triadic is a grid-based puzzle game about pushing and matching colored blocks in groups of 3 or more. Blocks are removed from a level after being matched, so the goal in each level is to remove all the blocks (excluding the grey ones). There are also color changers that change the color of one block to that of another block. The three colors used (blue, yellow, red) form a triadic color scheme, hence the game's name. Triadic has a total of 20 different levels with increasing difficulty.
