Pragmatic Play's 6x5 mythology slot uses tumbling reels and expanding multipliers to shape wins across ways to win. It returns 96.50% to players and brings wins that come less often and can be much bigger.

Gates of Olympus 1000 uses tumbling reels. Gates of Olympus 1000 takes you to ancient Greece on a 6-reel, 5-row grid where wins form across 20 payline multipliers rather than fixed lines. Released in late 2023 by Pragmatic Play, the slot combines a mythology theme with a distinctive Tumble mechanic: winning symbols vanish and new ones drop in from above, potentially building multiple wins from a single spin. Random Multiplier orbs land during these tumbles, stacking their values across the entire sequence.
High volatility means bigger swings between spins. This is a high-volatility slot where wins come less often and can be much bigger. You'll find it suits players with a longer bankroll who can handle quieter stretches between payouts. The betting range from NZ$0.20 to NZ$125 per spin gives flexibility, though the game's volatility means smaller wins happen less frequently. The mythology theme and complex bonus structures appeal to experienced players rather than those seeking steady, modest returns.
Your multiplier keeps growing in Free Spins. Free Spins shape your biggest opportunities here. Trigger them with 4 or more Scatter symbols landing anywhere on the reels, and you'll receive 15 free spins where a crucial difference takes hold: Multiplier orbs never reset their value during the entire bonus round. Every orb that lands permanently adds to your total multiplier, which keeps growing throughout the round. Land 3 or more Scatters again during the bonus to add 5 more spins and keep the multiplier climbing toward the 15000x cap.

Multiplier orbs land randomly with values from 2x to 1,000x, summed and applied to your full tumble sequence total.

This mode doubles how often Scatters land naturally via extra Scatter symbols on special reels. Buy Free Spins is not available while Double Chance is active. Double Chance runs at 96.50% RTP.
RTP is a long-run average across many thousands of spins. Each figure applies only to the way you choose to play: the standard game runs at one RTP, and buying the bonus runs at another.

When scatters arrive. The bonus round arrives without pattern or warning. Two sessions might see four scatters within ten spins, or none in a hundred. No frequency is guaranteed, and you cannot predict when Free Spins will land.
Trust maths, not your session. One session might end with a win well below the average, or one above it. The RTP of 96.50% is measured across millions of spins, not your own. Your next few hours could swing either way.
Know the maximum, not your win. The maximum win of NZ$1,875,000 at the top bet is a ceiling, not a target. It arrives so rarely that chasing it is not a plan. Most sessions will end far beneath it.
You've found the slot and want to know what happens before you stake your first spin
Budget before spinning. Decide how much you can afford to lose before you stake your first spin. Your budget stays with you when multipliers build or free spins retrigger, so knowing your limit helps you stick to it.
Decide when to step back. Set a point where you'll stop playing, win or lose. When a bonus round multiplier climbs or you hit a big tumble, stopping becomes harder—decide in advance when you'll walk away.
Control through your account. Use Viperspin's deposit limits and loss limits to keep your account in check. These tools stop you from spending more than you planned, session by session.
Pause or exclude yourself. If the game stops feeling like fun, take a break or use self-exclusion. Viperspin offers cooling-off periods and links to the Gambling Helpline New Zealand, The Problem Gambling Foundation and the Multi-Venue Exclusion Programme.
