Rad Respins, Toxic Spread & Mutation Multipliers
Rad Maxx drops you onto a 5x5 grid running the 360 Wins mechanic. You start with a single Pay Direction Arrow pointing right, so at first wins only pay left to right across matching symbols. That's the floor, not the ceiling — the whole game is about switching on the other three arrows.
Wild Plus is the symbol that opens things up. Land one and it flips on one to three extra Pay Direction Arrows: right to left, top to bottom, bottom to top. With all four live, the same grid gets read from every direction at once, which is where the 360 in 360 Wins comes from. One matching run of symbols can now pay up to four times over.
Then there's the Crazy Cat wild. It substitutes for regular symbols and carries a random multiplier from x2 up to x20. Drop more than one Crazy Cat into the same win and the multipliers don't add — they multiply, so two x20 cats stack into a x400 boost. Three free spins modes round it out: each hands you 10 spins with all four Pay Direction Arrows locked on for the whole round plus sticky wild multipliers, so those Crazy Cat values keep compounding. That's how the 12,500x ceiling gets reached on 96.31% RTP, medium-high-volatility math.

Bonus Mechanics Explained
5 mechanics drive the 12,500x max win. Here's exactly how each one works.
360 Wins & Pay Direction Arrows
How to Trigger
Active every spin. One arrow (left to right) starts live; more switch on when Wild Plus lands.
What Happens
Rad Maxx reads the 5x5 grid through Pay Direction Arrows sitting outside the reels. By default only the right-pointing arrow is on, so wins pay left to right. Each Wild Plus symbol can flip on one to three of the remaining arrows — right to left, top to bottom, bottom to top. With all four live, one run of matching symbols pays in every direction it appears, which is where the "360" comes from. The arrows stay on for that single spin unless you are in free spins, where all four hold for the whole round.
Multipliers
No multiplier on the arrows themselves. Their value is combinatorial: a win that pays once with one arrow can pay up to four times over with all four active.
Odds (est.)
Two or more arrows on a base spin: ~1 per 6 spins. All four arrows in the base game: ~1 per 40 spins. All four are guaranteed for the full free spins round.
Variants
Base game: arrows reset each spin based on Wild Plus. Free spins: all four arrows locked on from spin one to the last.
Strategy
The base game feels thin until Wild Plus lands, so treat the extra arrows as the swing moments. The real value comes in free spins where all four are permanent and every Crazy Cat multiplier gets counted from more directions.
| Grid | 5 reels × 5 rows |
| Default Arrows | 1 (left to right) |
| Max Arrows | 4 (up to 360 ways) |
| Arrow Source | Wild Plus symbol |
| Free Spins | All four locked on |
Crazy Cat Wild Multipliers
How to Trigger
A Crazy Cat wild lands anywhere on the 5x5 grid in base or bonus play.
What Happens
Crazy Cat symbols are wilds that substitute for any regular paying symbol, and each one carries a random multiplier from x2 up to x20. When a Crazy Cat sits on a winning line, that line pays at its multiplier. Land two or more Crazy Cats on the same win and the multipliers do not add — they multiply together. Two x20 cats become x400, three mid-value cats can push far higher. Combined with several Pay Direction Arrows counting the same symbols, the multiplier math stacks fast.
Multipliers
Per wild: x2, x3, x5, x10, x15 or x20 at random. Multiple wilds in one win multiply into each other — no cap beyond the 12,500x game ceiling.
Odds (est.)
Single Crazy Cat on a spin: ~1 per 7 spins. Two on the same win: ~1 per 55. A combined multiplier over x100: ~1 per 900.
Variants
Same rule in base and bonus, but in free spins Crazy Cat wilds turn sticky and stay on the grid, so their multipliers keep compounding across the round.
Strategy
Chase the free spins, not the base game. A single high-value Crazy Cat rarely matters on its own — it is the stacking of two or three sticky cats with all four arrows live that produces the top payouts.
| Multiplier Range | x2 to x20 |
| Multiple Wilds | Multiply together |
| Single Wild Odds | ~1 per 7 spins |
| Two-Wild Win | ~1 per 55 |
| Free Spins | Wilds turn sticky |
Wild Plus Symbol
How to Trigger
A Wild Plus symbol lands anywhere on the grid.
What Happens
Wild Plus does double duty. It acts as a wild for line wins, and it activates extra Pay Direction Arrows — one, two or three of them per symbol, on top of the default arrow. That is the only way to unlock the top, bottom and right-to-left directions in the base game. Land enough Wild Plus symbols on one spin and you can open all four arrows for a full 360-way read of the grid.
Multipliers
No standalone multiplier. It feeds the 360 Wins system by adding directions, which multiplies how many times a winning symbol run gets counted.
Odds (est.)
A Wild Plus on any base spin: ~1 per 9 spins. Enough Wild Plus symbols to open all four arrows at once: ~1 per 40 spins.
Variants
In free spins the arrow work is already done — all four are on from the start — so Wild Plus there simply acts as an extra wild on the grid.
Strategy
Wild Plus is the base-game trigger you are waiting for. Until it lands you are stuck paying one direction only. It is worth staying in a session long enough to hit the arrow-opening spins.
| Adds Arrows | 1 to 3 per symbol |
| Doubles As | A wild |
| Base Odds | ~1 per 9 spins |
| All Four Arrows | ~1 per 40 spins |
| Free Spins Role | Extra wild |
Free Spins
How to Trigger
Land 3 or more Scatter symbols anywhere on the grid.
What Happens
Three scatters award 10 free spins, and the whole round runs with all four Pay Direction Arrows locked on from the first spin. On top of that, every Crazy Cat wild that lands turns sticky and holds its multiplier in place for the rest of the round. As sticky cats build up, later spins can read a grid dense with x2 to x20 multipliers from all four directions at once. Rad Maxx ships three free spins modes in total, each tuned to a different balance of spins and multiplier weighting.
Multipliers
No global counter. The climb comes from sticky Crazy Cat wilds multiplying together across the round — a late spin with three or four sticky cats live can produce a several-hundred-x hit.
Odds (est.)
Natural trigger: ~1 per 190 spins. 4-scatter entry (extra spins): ~1 per 1,800 spins. Retrigger from more scatters mid-round: ~9%.
Variants
Three free spins modes exist, split by scatter count and buy option. All share the all-arrows-on and sticky-wild rules; they differ in spin count and how aggressively multipliers are weighted.
Strategy
Play the full round every time — the value is back-loaded once several sticky cats are on the board. Early free spins can look flat; the tail is where the 12,500x cap comes from.
| Trigger | 3+ scatters |
| Base Spins | 10 |
| Arrows | All four locked on |
| Sticky Wilds | Crazy Cats hold |
| Modes | Three variants |
Feature Buy
How to Trigger
Player purchase from the base-game menu, where the operator allows it.
What Happens
Instead of waiting for three scatters, you can buy straight into the free spins for a flat 100x stake. The bought round runs the same rules as a natural trigger — 10 spins, all four Pay Direction Arrows on, sticky Crazy Cat wilds. It is restricted in the UK, Netherlands and several other regulated markets, so the button is greyed out where local rules ban feature buys.
Multipliers
Identical mechanics to a natural trigger. The value comes entirely from how many sticky Crazy Cat wilds stack during the bought round.
Odds (est.)
No trigger randomness — always available where legal. The variance is in the outcome: many buys return under the cost, a small tail clears well over 1,000x.
Variants
Buy cost and spin count follow whichever of the three free spins modes the buy is tied to. Availability depends on jurisdiction.
Strategy
A feature buy is a flat wager on free-spins variance. Bankroll for several buys rather than one, since a single bought round can easily miss the sticky-wild stacks that pay.
| Cost | 100x stake |
| Buys | Free spins round |
| Arrows | All four on |
| Sticky Wilds | Active |
| Restricted | UK, NL, others |
