How to Play Rad Maxx
Six steps from your first spin to the 12,500x cap. Spread Toxic Wilds, cascade Rad Respins, trigger Wasteland Free Spins for the persistent Mutation Multiplier.
Set Your Bet
Open Rad Maxx and adjust your stake between $0.10 and $100. High volatility (5/5) — among Hacksaw's most volatile releases. 78% dead spins in base game. Bankroll for the dead-spin rate; the Toxic Wild + cascade combos are what fund the swing wins. Budget for at least 250 spins at your chosen bet level.
Spin the 6×5 Wasteland Grid
Hit spin or use autoplay. The 6x5 grid fills with post-apocalyptic symbols (Mutant Skull, Gas Mask, Radiation Barrel, Rusted Gear, Chain Link, Bolt, Bullet, Wire, Scrap). Wins resolve through Cluster Pays — 5+ matching symbols touching horizontally or vertically. Watch for Toxic Wilds and Scatters (radiation barrels).
Watch Toxic Wilds Spread
When a Toxic Wild lands, it irradiates 1-3 random adjacent positions in base game (2-6 during Wasteland Free Spins). Those neighbouring symbols mutate into wilds and stay wild for the Rad Respin chain duration. A center-position Toxic Wild can transform an entire 7-symbol pocket into wilds in a single spread.
Cascade Through Rad Respins
After any winning cluster, a Rad Respin occurs — winning symbols lock while new ones drop in. If the new symbols form another cluster, another respin triggers. The chain continues until no new wins form. Long chains of 5-8+ respins on a single base spin happen during dense symbol distributions.
Trigger Wasteland Free Spins
Land 3+ scatters anywhere on the grid for 10 Wasteland Free Spins. Two things change: Toxic Wild spread doubles to 2-6 adjacent positions, and a Mutation Multiplier counter starts at 1x. Each winning cluster — including every cluster inside a Rad Respin chain — adds +1x to the multiplier. The counter never resets between spins.
Decide on the Bonus Buy
Wasteland Free Spins where available costs 100x (avg return ~~80x, RTP 96.20%). The buy maintains base RTP — typical Hacksaw structure. Single-tier only — no premium buy with extra spins or guaranteed multipliers. Restricted in UK, Netherlands, and several other markets. The 12,500x cap requires extreme variance.
Symbol Paytable
Premium post-apocalyptic icons (Mutant Skull, Gas Mask, Radiation Barrel) carry the highest cluster payouts; mid-tier (Rusted Gear, Chain Link) fills the middle; low-tier (Bolt, Bullet, Wire, Scrap) and Rad Maxx Wild + Scatter complete the 6x5 cluster grid.
Bonus Features Explained
Each feature plays differently. Here's what actually happens — no marketing fluff.
Toxic Wilds
Toxic Wild symbols spread radiation to 1-3 adjacent positions, turning them wild. A single Toxic Wild in the center can create a 4-wild cluster. During Wasteland Free Spins, spread range doubles.
Rad Respins
After any winning cluster, a Rad Respin occurs — winning symbols lock while new ones drop in. If the new symbols form another cluster, another respin triggers. The chain continues until no new wins form.
Wasteland Free Spins
3 scatters trigger 10 Wasteland Free Spins. Toxic Wilds have doubled spread range. Mutation Multipliers start at 1x and increase by 1x with each winning cluster. The multiplier never resets.
Mutation Multipliers
Each winning cluster during Wasteland Free Spins adds 1x to the running multiplier. Combined with Toxic Wild spread chains, the multiplier can climb rapidly. This is where the 12,500x becomes reachable.
Quick Strategy Tips
Bankroll for the brutal variance. High volatility (5/5) produces 78% dead spins in base game. Wasted Toxic Wild spreads (about 1 in 4 spreads radiate into already-cleared cells) add to the cost. The Toxic Wild + cascade combos fund the swing wins. Budget for at least 300 spins at your chosen bet level.
Know the RTP. At 96.22%, this slot sits at industry standard. Below Hacksaw average (most are 96.25%+). Bonus Buy version: 96.20%. Some operators may run lower variants — verify in the game info screen before spinning.
Watch grid composition pre-spin. Long chains are where base-game returns come from. Watch for low-pay symbol density on the grid pre-spin — clusters of Bolts, Bullets, and Wires trigger longer cascades than premium-symbol heavy boards. Premiums pay more per cluster but produce shorter chains.
Mutation Multiplier favours patient stakes. The first half of Wasteland Free Spins is mostly counter-building; meaningful cluster payouts arrive in the back half once the multiplier crosses 8x-10x. Don't panic at low early-bonus returns — the math compounds heavily on the tail end. Top 5% of bonuses end with 18x+ multipliers; top 1% with 30x+.
