User-friendly arrow buttons change your stakes from just 0.25 per spin right up to the maximum of 125.00. But here’s where the Power Bet option becomes important. Click the ‘Activate Now’ button, and you see three options.
For 10x your per spin bet, you can activate 15 Power Spins. For a wager equal to 20x the stake, 20 Power Spins play out. Make a bet of 40x to trigger 25 Power Spins, where you'll have an even bigger chance of winning.
The spins start with the number of rows in The Green Machine Deluxe Power Bet slot machine expanding from three to four. On each subsequent spin, one further symbol position above the four rows becomes active, and after every fifth spin, you have a whole extra row in play. At the maximum Power Bet, by the end of the 25 spins, all eight rows of symbols are active.
Spin the reels and watch as the various win multipliers tumble from above. The chances of landing a multiplier increase with extra rows of symbols in play. Once a sequence of spins comes to an end, the reels revert to a 5x3 layout, and you can either keep this size, or go for another Power Bet.
The return to players percentage varies, from a respectable 95% with three active rows, to an excellent 96.5% with all eight rows activated.
