What are cluster pays?

Short Answer: 'Cluster Pays' is a mechanic where you win by landing groups of matching symbols that touch each other horizontally or vertically, rather than lining them up on fixed paylines. It is typically played on larger grids (e.g., 7x7) and feels more like a mobile puzzle game (like Candy Crush) than a traditional slot.

1. How to Win

In a standard slot, you need 3 symbols in a row from left to right. In a Cluster Pay slot (like Reactoonz or Sugar Rush), you usually need a minimum of 5 matching symbols touching side-by-side or top-to-bottom. A block of 15+ symbols usually pays the highest tier prize.

2. The Cascade Effect

Cluster slots almost always use 'Cascading' or 'Avalanche' mechanics. When a cluster wins, the symbols explode/pop and disappear. The symbols above drop down to fill the empty spaces. If this creates a new cluster, you win again. This allows for long chains of wins from a single spin.

3. Cluster vs. Pay Anywhere

This is a common confusion. Gates of Olympus is a 'Pay Anywhere' slot (you need 8 symbols anywhere on the screen, they don't have to touch). Sugar Rush is a 'Cluster Pay' slot (they MUST touch). Cluster slots require more spatial luck, whereas Pay Anywhere slots just require the symbols to appear.

4. Why Players Love Them

These games are engaging because they break the monotony of spinning reels. They often feature 'meters' on the side of the screen that fill up with every winning cluster. Filling the meter usually triggers a 'Super Feature' or 'Gargantoon' that adds massive Wilds to the grid for a guaranteed big win.
