At the start of the game, players have one Pokémon for which the bingo sheet is named that has two EP or Entry Points. Players also have two empty Master Balls and a fourth slot with no ball or Pokémon in it.
The player can choose any square out of the sixteen to begin at. From that square and any other cleared squares the player has in the game, only movement to adjacent squares is allowed. When the square is gray with a question mark on it, there is an item underneath. When it is colored and has a type name written on it, there is a Pokémon of that type and possibly a second type underneath and by moving to that square, will have to battle it. The player is to send in a Pokémon to this battle, and that is to have at least 1 Entry Point (EP). When it does, it can either take on the enemy Pokémon and attempt to defeat it, or the player can throw a Master Ball to capture the enemy Pokémon. The Pokémon will then join the player's team automatically and have two EP.
By clearing lines of four, the player will move up levels on the payout for Poké Coupons. If all ten possible lines are cleared, the Bingo Sheet would be cleared.
If a card that's been cleared at least once is replayed, the squares are shuffled randomly to make the game a little harder. This also ensures people who've taken notes on a card can't use the same set of notes to determine positioning in subsequent games on the same card.
Additionally, if a player clears all 10 of the standard cards (the Bonsly Card is not required), an additional more difficult method of gameplay is unlocked where the player's next choice must be in an adjacent space to the one selected previously. If a player can't make a move in this mode, the game ends.
