Doubledown Casino offers free chips to anyone who registers for an account through a Facebook profile, as of 2015. Additional free chips are earned each day a person logs into the game, with bonus chips awarded if she invites a friend to play. Doubledown Casino is not a gambling website, so the free chips may never be exchanged for actual money no matter how many jackpots are won.
Doubledown Casino allows unregistered guests to play as well. These guests receive some chips in order to sample the game, but do not get the bonuses for logging in or referring a friend. Players can also purchase chips with credit or debit cards. Discount codes are available on sites such as PromotionCode.org, but these only make purchased chips cheaper, not free.
Doubledown Casino offers a wide variety of free casino games, including slots, blackjack, poker, bingo and roulette. The company includes over 30 different slot machine games, including Spirit of Christmas Slots, Skyrocket Slots, Lounge Loot Slots, DaVinci Diamonds Slots and Wolf Run Slots. Doubledown Casino also offers live slots tournaments. The company's blackjack offering is a simplified version in which players are limited to three cards in their attempts to get 21 and beat the house.
Poker at Doubledown Casino is available in both a video version and a live version against other human players. The live version is available in three sets of rules: Texas Hold 'em, Pot-Limit Omaha and Five Card Draw. The company's bingo games feature customizable game art, bobbers, playing cards and themed rooms. Strategy advice is available for all of the company's games.
