The blocks are shaped like various Pokémon which fall onto both screens; however, only the blocks on the bottom screen can be moved and matched.
The blocks can be moved upwards, but will instantly fall back down if a match isn't made. If four of the same Pokémon are in a row, a match is made and those Pokémon will vanish.
When a match of four is created, a Trozei Chance (or Link Chance) Icon will appear. When that happens, match-ups of three Pokémon are allowed for about 2 seconds. If a match of three is made during that time, match-ups of two Pokémon are allowed as well for as long as the player continues to make links every two seconds.
