April was a huge month for B2B software provider Endorphina, with the release of three new slot games and another to come.

The Prague-based Endorphina, which offers a wide range of Flash-based slot games for online casinos, launched its third online slot game, Cuckoo, on April 18, right after the release of the space-themed 2027 ISS on April 12, which was preceded by the emoticon-inspired Slotomoji. Less than a week after its release, Cuckoo has already awarded two lucky players with some big wins!

DIRK17 was the first lucky player, winning 40,000 EUR while playing the latest release at starcasino.be, while a second lucky player at PokerKlas played the max on Cuckoo and won big when he bet was multiplied by X2400; the highest possible multiplier in the game. Both big wins occurred during the unique alarm feature, which is the main feature of the game.

Set entirely inside a clock, Cuckoo’s theme is all about time. The symbols, reel set, and background appear as if they are made of porcelain. Named for Cuckoo clocks, the game is a 5 reel and 10 pay line slot machine and is available on desktop, tablet, and most other mobile devices.

To trigger the alarm/bonus feature, three scatter symbols must be landed on reels 1, 3, and 5 simultaneously. When the feature is triggered by the player, a big winding clock will appear that has an alarm set at the start of the bonus game. The player doesn’t’ know what time the alarm is set for and has a chance to guess by placing the hour hand somewhere on the dial. The closer the player gets to the alarm, the higher the multiplier of the bet. If the hands of the clock set the alarm off, the player loses the multiplier and the feature ends. If the alarm doesn’t go off, the player collects the win and has the opportunity to play another round.

The player can play a max of two rounds on the alarm feature. And if a player is lucky enough to win the max, 2400x multiplier, the feature ends.

While Cuckoo’s design and graphics are amazing and the gameplay is smooth, the thing that will make you a repeat player is the unique alarm feature and its big win potential. Many of Endorphina’s games are highly volatile, meaning players may go quite some time between decent wins, but when they do pay out, it’s usually a stunning amount.
