Hacksaw Gaming's explosive 7x7 cluster pays slot where rockets shatter symbols and leave multiplier trails up to 75x. Three rockets trigger launches in base game, while every single rocket fires during 8 free spins.
Watch for the silver UFO that randomly appears after rocket launches. Its cyan beam removes 20+ symbols from the grid, creating massive cascade opportunities with new symbols dropping down.
The core mechanic revolves around three rocket types that appear on the 7x7 grid. When three or more rockets land, they launch vertically, destroying all symbols in their path. Each destroyed position transforms into a multiplier that remains for the entire spin sequence.
Rocket 1 leaves 1x-5x multipliers in cyan trails. Rocket 2 creates orange paths with 10x-20x multipliers. Rocket 3, the purple variant, generates the highest 25x-75x multipliers. When multiple multipliers overlap a winning cluster, they add together before multiplying your win - creating potential for massive payouts when rockets cross paths.
Connect 5 or more matching symbols horizontally or vertically to form winning clusters. Planets pay more than crystals - red and green planets offer up to 60x for 15+ symbol clusters. The multicolored wild vortex substitutes for all regular symbols, helping complete clusters across the grid.
After each win, symbols in clusters vanish, triggering cascades. New symbols drop from above, potentially landing on multiplier positions left by rockets. This cascade continues until no new clusters form, with multipliers persisting through the entire cascade sequence for compound wins.
Landing 3 purple spaceship scatter symbols awards 8 free spins where every single rocket automatically launches. No need for three rockets to trigger - even a single rocket fires immediately, guaranteeing multiplier trails on every spin.
During free spins, the UFO feature appears more frequently. Multiple rocket launches per spin create overlapping multiplier grids. With guaranteed launches and persistent multipliers through cascades, free spins deliver the slot's biggest win potential up to the 10,000x maximum.
After any rocket launch, a silver UFO may appear above the grid. Its cyan beam removes between 20 and all symbols from random positions, leaving empty spaces. New symbols cascade down to fill gaps, potentially landing on existing multipliers from rocket trails. The UFO activates in both base game and free spins, adding an extra layer of win potential when rockets have already created multiplier positions.
Five crystal types (pink, blue, yellow, green, purple) form the low-paying tier, worth 0.01x-8x bet for 5-15+ clusters. Planet symbols pay significantly more - purple, blue with rings, yellow, red, and green planets deliver 0.025x-30x for similar cluster sizes.
Maximum clusters of 15+ symbols pay 8x for crystals and up to 30x for premium planets. While base values seem modest, the real winning power comes from multiplier combinations. A 15+ red planet cluster hitting multiple 75x multipliers can deliver massive payouts approaching the 10,000x ceiling.
Skip straight to free spins for 129x your bet. The bonus buy RTP increases slightly to 96.34%, making it mathematically favorable for players seeking immediate rocket launching action. Eight spins with guaranteed rocket fires and multiplier trails offer direct access to the slot's highest win potential.
