Slot machine

Slot machines are gimmicks that appear in the Sonic the Hedgehog series.

Sonic the Hedgehog 2
Slot machines make their first appearance in Casino Night Zone of Sonic the Hedgehog 2. In order to activate the slot machine, the player must jump into the three parallel bars directly above the gimmick. The results from various combinations on the slot machines are:
 * 3x Tails: 25 rings
 * 3x Eggman/Jackpot + 2x Eggman/2x Jackpot/Eggman: Lose 100 rings
 * 3x Sonic: 30 rings
 * 3x Jackpot: 150 rings
 * 3x Bar: 20 rings
 * 3x Ring: 10 rings
 * Jackpot + 2 of the same except Eggman = twice the original amount
 * 2x Jackpot + everything except Eggman = 4x the original amount

Sonic & Knuckles
The slot machine appears only in one Bonus Stage in Sonic & Knuckles. It functions the same way it did in Sonic the Hedgehog 2, except Knuckles' head is added.

Sonic Colors
In this game, slot machines are gimmicks that appear only in the Sonic Simulator. In order to activate it, the player must Homing Attack or Spin Jump into the lever on the left. If three identical slots appear when they stop spinning, the machine "dances", and the player receives that item.

Sonic & All-Stars Racing Transformed
Slot machines appear on the loading screen before each race. If the player has at least five All-Star coins, he/she is able to spin the slot machine. Should the three slots match, a new item is obtained. The player can also win an item at the start of every lap or start with an item at the start of the race. If not, the player does not earn anything, and can spin once more if he/she has the required number of coins. If the player has a determined amount of coins, but they are not enough, it cannot spin the slot machine.
