4Squad slot
4Squad is a Red Tiger slot released in 2020, played on a 7x6 grid where matching symbols pay in clusters instead of along lines. Four superheroes, Quake, Strike, Burst and Beam, each own a coloured meter that fills when clusters in their colour win. Fill all four during one spin and the game moves into Superhero Mode, a single free spin in which the whole squad acts together.

How 4Squad plays
Every symbol on the grid belongs to one of four colours, and Red Tiger splits them into four low-paying and four high-paying symbols. Above them sits a single highest-paying symbol that stands apart from the colour system. Wins come from groups of matching symbols that touch, as in any cluster pays slot, and one spin can carry on through several consecutive wins.
This is where the meters matter. Each winning cluster pours into the meter of its colour, and that progress is kept for as long as the run of wins lasts. Once the spin ends, the meters start again from empty on the next one. The top symbol pays well but adds nothing to any meter, so a spin full of it can leave the heroes waiting.
Quake, Strike, Burst and Beam
Each hero steps to the front of the reels when their bar is full. Quake, the green hero, sweeps every low-paying symbol off the grid and lets new ones fall into the gaps. Strike, in blue, swaps a random number of symbols for wilds. Burst, the red hero, picks one symbol already on the reels and clones it a random number of times. Beam, in yellow, works on the payout itself, applying a multiplier between 2x and 10x to the current win.
Superhero Mode
Superhero Mode is the reward for filling all four meters before a spin ends. It awards one free spin, and on that spin the low-paying symbols are taken out of the game while every hero feature is triggered. Instead of waiting for a single colour to build up, you get Quake, Strike, Burst and Beam on the same spin, working on a grid made only of the higher symbols. With just one spin on offer, the whole bonus is decided by how that grid lands and how the four features fall into place.
4Squad compared with Thor’s Lightning
Thor’s Lightning is another Red Tiger cluster game, but it gives Thor a 7x7 grid and needs five or more matching symbols side by side for a win. The two games reach their bonuses in different ways. Thor’s Lightning hides a block of tiles in the middle of the grid, and clearing it leads to one of two free spins rounds, Valhalla or Muspell. 4Squad instead asks you to fill four colour meters in a single spin, and its bonus is one spin long rather than a full round. Its top prize is also lower than the one Thor offers.
| Game | Grid and pays | Route to the bonus | Maximum win |
|---|---|---|---|
| Thor’s Lightning | 7x7, cluster pays | Clear the block of tiles in the centre of the grid | 1,848x stake |
| 4Squad | 7x6, cluster pays | Fill all four hero meters in one spin | 1,279x stake |

Frequently asked questions
What is the 4 Squad slot?
It is a superhero game from Red Tiger, written by the studio as one word, 4Squad. The squad is four colour-coded heroes, and the game is built around charging them up: every win in a hero’s colour adds to their bar, so the slot asks you to watch the colours on the grid as much as the size of each cluster.
Who are the heroes in 4 Squad?
Quake is green, Strike is blue, Burst is red and Beam is yellow. Two of them change the symbols, one creates wilds and one adds a multiplier, so each full bar does something different to the grid. In normal play only the heroes whose bars fill will act, which is why a single spin can show anything from none of them to all four.
Do the meters in 4Squad carry over to the next spin?
No. The bars keep their progress while a run of consecutive cluster wins continues, but they empty once that spin is over. Every spin starts the charge from nothing, so the free spin in Superhero Mode can only come from a single spin in which all four colours win often enough to fill their bars.
