Dragons Clusterbuster™ by Red Tiger Gaming is a 9-reel slot built around cluster wins rather than fixed paylines. The game uses a high-volatility format and an RTP of 96%, with bet sizes ranging from 0.1 to 200. Its main feature is an inactive cluster of locked tiles, which opens as winning clusters are formed beside it.
When outer tiles are unlocked and broken, the cluster can be busted open to reveal its prize. The slot also uses Chain Reactions, so symbols that form a win disappear and are replaced by new symbols dropping into place, creating the possibility of additional wins in the same round.
The demo version is available for players who want to play for free and practice before playing for real money. It provides a way to review the cluster mechanic, locked-tile feature and repeated symbol drops before placing a stake.
