3 Reactors of Doom
3 Reactors of Doom is a Qora video slot set on a frozen city street, with gutted buildings and green sludge behind the reels. It plays on 5 reels and 4 rows with 50 paylines, and the grid opens to 6 rows and 100 paylines during the Expansion features. Wins pay from left to right, starting on the leftmost reel. The RTP is 94%, the volatility is high, and the top win is 6,000 times the bet. Bets run from $0.20 to $200.
The survival gear tops the paytable, led by the backpack, then the first aid kit and the Geiger counter together, then the canned food and the flashlight, with the corroded royals below, A, K and Q ahead of J, 10 and 9. The gas-masked figure is the Wild and stands in for every paying symbol. It does not cover the Biohazard Coins, which land in green, purple and red.
Three reactor pipes sit above the reels, one to each coin colour, and any coin that lands can set off its feature. Expansion awards 5 free spins on the wider grid, where a Wild fills its reel and some are worth x2 or x3. Multiplier awards 5 free spins under a count that starts at x1 and climbs by 1 a spin. Jackpot awards 10 free spins, where coins reveal letters for MINI, MINOR, MAJOR and GRAND.
Coins of different colours can trigger together, and seven variations are possible. Two features award a Super Feature that runs both sets of rules, and all three award the Mega Feature over 10 free spins. Jackpot Multiplier Coins raise the value of a single jackpot. The Bonus Buy sells a random single feature, a random pair or the Mega Feature.

Qora's 3 Reactors of Doom drops you onto a frozen city street, with wrecked buildings and green sludge under a yellow sky. You play 5 reels and 4 rows with 50 paylines, and the grid stretches to 6 rows and 100 paylines when an Expansion feature runs. Wins pay left to right from the leftmost reel. The RTP is 94%, the volatility is high, and your top win is 6,000 times your bet. You can bet from $0.20 to $200.
Your best payer is the backpack, then the first aid kit and the Geiger counter on level footing, then the canned food and the flashlight, with the rusted royals at the bottom where A, K and Q sit above J, 10 and 9. The hooded figure in the gas mask is your Wild, and it fills in for every paying symbol. It leaves the Biohazard Coins alone.
Keep an eye on the three reactor pipes above the reels, one to each coin colour. Green coins open Expansion, 5 free spins on the bigger grid where every Wild fills its reel and a few are worth x2 or x3. Purple coins open Multiplier, 5 free spins with a count that starts at x1 and adds 1 a spin. Red coins open Jackpot, 10 free spins where coins hand you letters for MINI, MINOR, MAJOR and GRAND.
Collect more than one colour and the round gets bigger. Two features give you a Super Feature with both sets of rules, and all three give you the Mega Feature over 10 free spins. Jackpot Multiplier Coins can push a jackpot higher. The Bonus Buy sells a single feature, a random pair or the Mega Feature. Fire up the reactors and see what is left standing.
