Star Clusters 2 Slot Game Review
Overview
In the base game, Star Clusters 2 casino slot game, starts each spin with a grid arranged in a 4×4 layout. During free spins, the initial size expands to 8×8. A winning cluster is formed when 5 or more matching symbols connect either horizontally or vertically, triggering various effects that will be detailed shortly.
The betting menu allows players to select a stake ranging from 20 cents to $20 per spin, with three RTP variants available, the highest being 96.63%. Regarding volatility, BTG has created a highly volatile mathematical model.
The pay symbols in Star Clusters 2 feature 7 distinct gems. These gems reward players with 0.1x to 0.8x the bet for clusters of 5 symbols, and up to 88x for clusters of 25 or more to 15 or more OAK hits – fewer symbols are required as you ascend the paytable.
Wild symbols can replace adjacent symbols, excluding Gold Wilds and scatters. Gold Wilds can substitute for any adjacent symbol except scatters and come with a random multiplier ranging from x2 to x100. The multipliers from all wilds within a winning cluster are summed and applied to enhance the cluster win.
Features
Reactions
When a winning cluster is created, each of the winning symbols is substituted with four smaller symbols. When wins are achieved with these smaller symbols, they are eliminated and new symbols of the same smaller size fall from above to take their place, filling all vacant spots on the grid. Reactions continue until there are no further wins, at which point the grid resets to its original size.
Free Spins
Scatters only appear on the grid as a result of reactions. Achieving 4 or more scatters in the base game grants 10 free spins, plus an additional free spin for each scatter beyond the fourth. Free spins feature an unlimited Wild Multiplier, starting at x1 and increasing by +1 with each reaction.
The current value of the Wild Multiplier is applied to all wilds involved in a winning cluster. The bonus round can be prolonged by landing scatter symbols. Obtaining 4 scatters rewards players with an additional +4 free spins, and 1 free spin is awarded for each scatter beyond the fourth.
Feature Buy
Star Clusters 2’s feature buy option allows players to immediately trigger the bonus round. There are two choices: 10 free spins for a cost of 60x the bet or 18 free spins for a cost of 160x the bet.
