Reviewed 27 October 2026. Reviewed by the Spinanigans editorial team, demo-play tested. How we review · DisclosureMore Twist Gaming (Juice) reviews · What is RTP? · What is volatility? · Best new slotsLab Leak is Twist Gaming's cluster slot, and it's built around a virus that spreads. It's one of the Juice titles that's new to a lot of casinos now. It's a seven by seven grid, five or more adjacent matching symbols pay, and the wild is a pink virus. When a virus wild takes part in a cluster win, it triggers the Virus Spread feature, a hold and spin that starts at the epicentre.
Every prize that lands causes a respin and infects the cells around it, and super virus cells spread multipliers to everything nearby, and those multipliers stack. When nothing new lands, you collect the total. Four or more bonus vials give ten free spins, two more for each extra, and Virus Spread can fire inside the free spins. The RTP is 96 percent, and the max win is 10,000 times in every mode.
The buy menu is wide. A free spins boost at 2.5 times, a virus boost at 5 times, a guaranteed Virus Spread at 30 times, and the full free spins bonus at 300. In our demo we played about 35 spins with nothing, then activated the 30 times Virus Spread on a one dollar bet and spun once. The grid filled with prizes and paid about 256 dollars, around eight times the cost.
That's one run, and a happy one, so it's not a promise. The feature looks great and is easy to follow. Fast, inventive and a lot of fun. 8.1 out of 10.
