ZapLab from ELK Studios electrifies players with its thrilling laboratory-themed adventure. Set in the mysterious lab of Dr. Mayhem, this high-volatility slot features a 7x7 grid with cluster pays and cascading wins. Packed with exciting features like Wilds, symbol upgrades, Shockwaves, and the Monster Meter, players can enjoy dynamic gameplay and thrilling modifiers. With an RTP of 94% and the chance to win up to 10,000 times your bet, ZapLab offers a charged gaming experience full of action and big win potential.
ZapLab does not have the usual paylines but requires matching symbols in a cluster (a.k.a. cluster pays) instead. The game has more features than most other slots, including Buy Feature, Cascading Reels, Cluster Pays, Collect Symbols, Colossal Symbols, Level Up, Monster Meter, Shockwaves, Symbol Upgrade, Xiter, and more. ZapLab also has a free spins bonus round and this is where you have the chance to win some serious cash.
The standard RTP (Return to Player) for ZapLab slot is 94% (Could be lower on some sites). This payback is rather low and considered to be below average for an online slot. Theoretically, this means that for every €100 put into the game, the expected payout would be €94. However, the RTP is calculated on millions of spins, which means that the output for each spin is always random.
The highest possible payout for this slot is 10000x your total bet which is very high and gives you the chance to win really big wins. The maximum possible win is also calculated over a huge amount of spins, often one billion spins.
ZapLab is a medium volatile slot, and ELK Studios rates the volatility to 3/5. Volatility, in the context of slot games, refers to how often and how much a slot game pays out. ZapLab may not result in the substantial wins that high volatility slots can deliver, but it does provide a more predictable and consistent winning experience. This makes ZapLab a popular choice among players who prefer a game with medium risk.
