DEQ Systems Corp.

This progessive blackjack side bet, which is made by betting credits on DEQ’s Progressive Bet Manager, pays players when they lose with any 20, based on the number of the dealer’s cards. Players win the progressive jackpot when they have a 20 and the dealer draws a seven-card 21.

The house advantage is adjustable, from 0% to 25%+, based on three factors: jackpot seeding strategies, adjustable paytables, and the frequency of "Magic Cards," which pay the players nominal credits (5-20) when they receive a displayed "Magic Card" in their first two cards. Other "hits," as determined by management, can be programmed into the game, which allow Hit Frequencies to vary from every 8 to 32 hands.
