One coin will only count the center row across, two coins will count all three rows across, and three coins will count all three rows across as well as both diagonals. One to three coins can be put in the slot machine each play. Slot machines in Generation II are similar to the ones from Generation I. It is possible to win a jackpot every time if replaying the situation from a save state, as the number of icons slipped is determined before the final reel is stopped, and therefore would not change. However, the game may cause the reels to randomly slip a few spaces, making it impossible to do so reliably. In FireRed and LeafGreen, reels run on a repeating cycle, so it is possible to predict and stop the reels on a desired outcome. If a player had a Berry in the top left spot and a Berry right next to it, and they had paid three coins, they would get 8 coins (one Berry going diagonal and two Berries going horizontal). Payouts are cumulative, so if a player lined up three Psyduck in one row and one Berry in a different row, they would receive 17 coins. In FireRed and LeafGreen, players can achieve the following payouts, which are calculated starting from the left reel:

Playing for 3 coins allows payouts on all three horizontal lines as well as two diagonal lines. Playing for 2 coins allows payouts on all three horizontal lines. Playing slot machines for 1 coin allows payouts only on the center line. Slot machines can be played for 1, 2, or 3 Coins. Slot machines in the Generation I games and Pokémon FireRed and LeafGreen consist simply of inserting coins and stopping the reels with the A button.
