Frenzy Clusters Slot by BGaming

Before a single symbol drops, you pick a hero. The roster is a row of glowing cards, with Golub the wizard pigeon, plus a dog, a goose, a goblin, a platypus, each one in a star hat and cape, and whichever you choose activates the special features for the round. You can swap heroes mid-session whenever you like, so the choice is never locked in. It's a cosmetic-feeling frame for what's underneath, but the cards and the flaming border give the whole thing a comic-book energy that carries into the cluster grid behind it.

That grid starts mostly buried. Chunky blue-grey rocks block a large share of the 7x7 board, and symbols only fall into the open cells, those bright potion bottles, blue skull hexagons, purple crystal-ball pentagons, green mushroom triangles and card tiles against a dark cave backdrop. A rock unlocks when a winning combination forms in a cell directly next to it, opening more room for the next tumble. In the base game that unlock lasts one spin only. The board reseals afterward, so you're constantly chipping the grid back open.

Wins come from clusters of four or more matching symbols touching vertically or horizontally. They pay, burst, and refill from above until nothing new connects. Single-symbol pays are modest on their own, topping out around 25x bet for a twelve-plus cluster of the best symbol, which tells you the headline 10,000x lives somewhere else. After a burst, one of three special symbols can spawn: a Rocket that wipes a full row or column, a Book that clears everything around itself, or a Sphere that removes one random symbol type across the entire board. They clear without paying, but they reshuffle the grid in ways a normal tumble can't.

Free Spins are the real engine. The number of scatters that triggered the round sets your starting multiplier, so three scatters open at x3, and that multiplier applies to every winning cluster and climbs from there as you unlock bonus multipliers and land more scatters. Rocks stay open for the whole bonus instead of resealing, which keeps the board large and the chains long. Three buy options feed into it: Regular at around 100x bet, the Mystery portal at roughly 137.5x that drops you into either tier, and Mega at 250x with the full grid and multipliers unlocked. Or stay in the base game and add the Buy Chance ante for +25% to push scatters in more often.
