The Firebird Double 27 slot game is a medium-variance slot machine with an RTP of 95.11%, which is on the somewhat low side. This is therefore an ideal option for players who like more challenging fare where payouts are less frequent. Getting started on the Firebird Double 27 slot online is easy because it is a fruit machine, which means it features the very basics of slot gameplay. Simply spin the reels in the hopes of landing at least three matching symbols on any of the game’s 27 paylines. Your win is then calculated by how much that symbol pays out and how much you’ve staked in the game between 0.20 and 100. The Firebird Double 27 online slot runs on a pay-both-ways format, so luckily for you, there are actually 54 paylines and every win is counted from left-to-right and from right-to-left. The titular firebird is of course the wild and can substitute for all regular symbols to form a winning line. There is also an exciting gamble feature, which is generally a feature found in fruit machines but which Synot Games has brought up to a more fresh and exciting level. Triggered after every win as an optional bonus, the gamble is a mini-game that asks you to pick between two cards. Guessing the correct card will double your total earnings, while an incorrect guess ends the game with a wallet worth zero. But what really sets the gamble bonus of the Firebird Double 27 slot machine apart is that you can keep on playing and risk it all up to five times! There is even an option to gamble just half of your earnings. Though there is no free spins bonus, this exciting feature is more than enough to keep you on your toes.
