Playtech offers a unique category of slots machines at its online casinos with a side game called Dollar Ball. This lotto type game requires an additional fixed bet and is played while the reels spin in the main game.

The Dollar Ball icon is located at the top right part of the screen. Players have to click the Enable logo in order to activate it. A set of numbers from 1 to 49 are displayed and players have to pick five of them. The numbers can be selected manually or players can click on Random pick for an automatic selection. Once the selection is confirmed the Dollar Ball Bet is automatically deducted from the players’ balance. Players must note that the Dollar Ball side game will be played along with every main game spin with the same numbers, until the numbers are changed or the side game is disabled.

The selected numbers are displayed in a row of white circles at the top of the screen. Once the slots game reels are spun the five drawn numbers will appear just above them. If any of the numbers match the selection, the circles containing these numbers will change color to green and the win amount will appear below. The payouts from the Dollar Ball game will be added to the player balance along with any winnings from the main game. Dollar Ball wins are paid according to the pay table for Dollar Ball which is displayed within the main game pay table.

Wins received from up to three matches are fixed wins and the amounts calculated by multiplying the side bet by the corresponding pay table multiplier. For a single match the multiplier is 1, for two matches the multiplier is 2 and for three matches the multiplier is 25. Four or more matches lead to progressive jackpot wins. A small percentage of each side bet, usually 10%, is added to the progressive jackpot pool. When a player gets four matches he wins 1% of the progressive jackpot amount. These partial payouts reduce the amount of the progressive jackpot. When a player gets five matches he wins the entire progressive jackpot. After a complete jackpot has been won, a new pool is started with the base or seed amount. Usually the seed amount is 10,000 times the side bet.
