While fundamentally the same as in the first two generations, the third generation introduced bonus games to the slot machine experience. The third generation is where slot machines began to become more complex. This guarantees the third reel to land on a 7. Very rarely, a Chansey will appear and use Egg Bomb to spin the third reel when two 7's are lined up.It will either line up and pay out the jackpot, or end up one space away from lining up to tease the player. The third reel will move by itself when two 7's are lined up.Several Golem will drop when two 7's are lined up.When one 7 displays on the reels, sometimes the second one will spin down to a 7 as well.In the Generation II games, several things can happen when 7's appear on a reel: The reels stop spinning when the player presses the A button. 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.
