Kollon is a puzzle game for the PlayStation Portable where players must clear blocks by matching four or more of the same color. New rows of blocks continuously push up from the bottom, requiring timely clears to prevent the blocks from reaching the top. The game features various modes, including multiplayer and arcade, with increasing difficulty as more rows are introduced, adding to the challenge.
Ultimate Block Party is a puzzle game series where blocks must be cleared. Every so often new rows of blocks will push up the current ones. Not clearing enough within a set time limit will force the blocks to the top of the screen, where the player will lose. Blocks can be cleared if at least four blocks of the same color are touching. The speed of new rows will increase as the game is played longer. The blocks which get cleared will result in the blocks above falling down. The game offers several different modes including a multiplayer and arcade mode.
