Bubble Trouble

Bubble Trouble by Yolted is a slot game built around a 9x6 hexagonal symbol grid, where matching bubbles connect in clusters of up to six directions. Winning symbols are removed and replaced through a refill system that can expand the play area to 9x12 rows during base play. The game uses a cluster mechanic rather than traditional paylines, with a high-volatility profile and a reported RTP range of 90% to 96%.

Players can use the demo version to play for free and practice before playing for real money. The feature set includes Bob the Dragon’s Pop, Bomb and Spikey abilities, which trigger after removing 30, 50 and 70 symbols respectively. These features clear selected symbols or grid sections and can help create larger cascades and improve the chance of reaching the bonus game.

The free spin bonus round starts when the word BONUS is formed on the grid. In this mode, wild multiplier symbols can appear on odd columns, rising up to 10x, with combined clusters reaching up to 100x. Free spins can be extended during the round, up to a maximum of 100, while the Pop, Bomb and Spikey mechanics remain active.
