Opal Fruits by Big Time Gaming is a love letter to 1980s space adventures, and it comes packed with the Triple Reaction mechanic. You're looking at a 6-reel slot with 5,625 paylines, a very solid 96.75% RTP, and high volatility gameplay. The name? It's a cheeky nod to the retro candy that eventually became Starburst — nice touch, right? Play for free in demo mode, no download needed.
Triple Reaction & Multiplier Wilds
Here's where it gets interesting. The Triple Reaction system makes its debut in Opal Fruits, built around a fixed 6x3 grid with two extra horizontal reels sitting above and below. Wilds only show up on those horizontal reels, and they come with 3x multipliers. When multiple wilds land on the same column, their multipliers stack by multiplying together. Four wilds on one horizontal reel? That's an 81x multiplier. Four on both reels at once? You're looking at a jaw-dropping 1,296x multiplier.
To get free spins, you need to spell out F-R-E-E across consecutive reactions — which awards 10 free spins with unlimited win multipliers. Each cascade bumps the multiplier up by 1x, and every time you hit a multiple of 10x, you get 5 extra free spins thrown in. The max win tops out at 36,600x your stake, which is seriously impressive. Bets range from $0.10 to $20, and the retro 80s soundtrack features original Williams Electronics Robotron and Defender sound effects — a great detail for nostalgia fans.
