Rotiki

Rotiki by Play’n GO is a video slot in the cluster pays format, played on a 6×8 grid. The symbols spin block by block from left to right, and instead of disappearing, winning clusters stick ("sticky") and trigger a respins feature as soon as five or more matching symbols are connected orthogonally. You receive three respins after the first cluster win and additional respins whenever a whole horizontal row block is filled. Wild symbols can help form clusters, and at the end of the respins, they trigger the "Tiki Magic": Hanumi connects two clusters, and Whakarei upgrades a cluster to a more valuable mask symbol. If you achieve this goal and fill the entire grid with winning symbols, the bonus feature "Treasure Room" is activated. There, you play a pick-and-click with stone tiles: from a total of 48, hidden multipliers, additional picks, or neutral fields are revealed, and a special mask symbol can instantly bring the multiplier to the maximum (×10). The maximum win is about 1,000 times your bet. Thematically, Rotiki takes place in a tropical island setting with Tiki and island motifs, vividly designed masks, and an atmosphere of discovery and adventure.
