Cash Lab Megaways is a high-volatility online slot from iSoftBet with an RTP of 95.99% and a maximum win of 20,000x.
iSoftBet frames Cash Lab Megaways around a fictional science lab that turns experiments into cash prizes, and the reel set backs up the joke: six vertically spinning reels sit alongside two horizontal tracker reels running along the top and bottom of the grid. That extra pair of reels pushes the number of ways to win to 200,704, well above the 117,649 a standard Megaways engine produces. Bubbling glassware, coiled tubing and a mild-mannered lab technician fill out the visuals, paired with a soundtrack that keeps pace with the reels rather than dominating them.
Wins are formed the usual Megaways way: matching symbols need to connect from the leftmost reel across consecutive reels, landing in any row. A full six-symbol connection on the royal card symbols pays between 0.4x and 0.75x the stake, while the coloured gemstone premiums - purple, green, blue and red - reach 1x to 5x for the same length of run. Two wild types appear on the grid: a standard rainbow wild and a Gold wild, both of which substitute for everything except the scatter and both of which tie into the reel-linking features described below.
Every winning combination triggers a cascade: the symbols involved in the win clear from the grid and new ones drop in from above, or from the side on the tracker reels, with the sequence continuing until a spin produces no further win. Layered on top of that is Max Megaways, a random base-game event that fills every position on the main reels so the full 200,704 ways are briefly guaranteed.
The tracker reels feed two linked features. When wild symbols land directly opposite each other on the top and bottom tracker reels, everything between them on the connecting main reel turns wild through the Wild Link feature. If one of the two triggering wilds is the Gold variant, Gold Link additionally applies a random multiplier to that reel, set higher than the number of symbols sitting on it.
Scatters do the heavy lifting for Cash Lab Megaways' free spins round. Four scattered symbols in the base game award 10 free spins, five award 15, and a full six award 20. The round opens with a single Sticky wild already placed on the upper tracker reel and a multiplier of x1 that climbs by one point after every cascade in a spin. Sticky wilds clear along with the rest of a winning combination but reappear for the next spin rather than staying gone. During the round, reels can also produce the letters L, I, N and K; collecting a full set adds another Sticky wild to the opposite tracker reel, extends the round by two spins, and resets the letter collection to start again.
Cash Lab Megaways carries a 96% RTP and a high-volatility profile, with a maximum win of 20,000x the stake and a hit frequency of 27.9%. Stakes run from 0.20 up to 20 per spin. Players who don't want to wait for scatters to land naturally can spend 100x the stake on a direct entry into the free spins round. Between the tracker-reel wild features and the escalating free spins multiplier, most of the game's win potential is concentrated in the bonus round rather than the base game.
