El Toro is a 3-reel slot game, and the pay table is displayed on the machine. It may be played in denominations of $.05, $.25, $.50, $1, and $5.
The bonus game consists of a matador on the left side of the pay table and a bull on the right side of the pay table. A player must make a 3-coin wager in order to be eligible for the bonus game. When a player receives a matador and a bull icon on the same spin wagering 3 coins, the Bullfight bonus game becomes active.
Players choose who they think will win the bull or the matador. Players make their choice by selecting only one of the icons on either side of the pay table. Once they have made their selection, the bullfight begins. The bull icon on the reel charges the matador icon. Either the bull will flatten the matador or the matador will successfully dodge the bull. The player wins the bonus (200 credits) if they have chosen the winner correctly. If the player makes the wrong selection, a nominal amount is awarded (10 credits).

In addition, a rose icon (wild) matches any symbol on the pay line except for the matador and bull icons.
