Reel Rush takes NetEnt's ways-to-win format and builds an entire game around one idea: what if the reels grew bigger every time you won? Released in July 2013, it starts you on a diamond-shaped grid (1-3-5-3-1 configuration) with just 45 ways to win, then expands up to a full 5x5 layout with 3,125 ways. The retro fruit-and-candy theme keeps things bright and simple while the expanding mechanic does all the heavy lifting.
How It Plays
The base setup is five reels in a diamond shape - one position on reel 1, three on reel 2, five in the middle, three on reel 4, and one on reel 5. That gives you 45 ways to win (1x3x5x3x1). Bets run from 0.50 to 100 per spin across those ways, so there are no traditional paylines to configure. You just need matching symbols on adjacent reels from left to right.
With a 28% hit frequency, you land a win roughly every three to four spins. That keeps the base game moving at a decent pace, which matters because wins are what drive the expanding mechanic. The symbols are a mix of strawberries, plums, oranges, and candy pieces on a bright pink and purple backdrop - unmistakably retro.
Re-Spins and the Expanding Grid
This is where Reel Rush comes alive. Every time you land a winning combination, you get a free re-spin and two new reel positions open up. Clouds puff away to reveal the extra spaces, changing the grid shape and increasing your ways to win.
You can chain up to five consecutive re-spins this way. Each one adds two positions, so the grid gradually shifts from that initial 45-way diamond toward the full 5x5 square. The progression goes roughly: 45 ways, then 135, 405, 1,215, and finally 3,125 ways on the fifth re-spin. Each stage gives you a better shot at forming winning combinations simply because there are more symbol positions in play.
The catch is that you need to keep winning. If any re-spin comes up empty, the sequence ends and the grid resets to the starting diamond shape for your next paid spin. It creates a genuine tension with each re-spin - you want that win to keep the expansion going.
Free Spins on the Full Grid
If you manage to win on all five re-spins in a single sequence, you trigger 8 free spins. These play out on the fully expanded 5x5 grid with all 3,125 ways active for every spin. No more worrying about the grid shrinking back - you get the maximum layout for the entire bonus round.
During free spins, wilds appear on reels 2 through 5 and substitute for all paying symbols. A star animation plays when a wild completes a winning line. The combination of full grid coverage and wild substitutions is where the bigger payouts tend to land, with the game capping out at 1,000x your total stake.
Getting to free spins requires five consecutive wins from a single starting spin, which does not happen often. But the 28% hit rate on the first spin gives you a reasonable starting chance, and each subsequent re-spin benefits from the growing number of ways.
Wild Substitution
Wilds show up on reels 2, 3, 4, and 5 during both the base game and free spins. They substitute for every other symbol in the game, and when a wild completes a winning combination you get a star burst animation to mark it. The absence of wilds on reel 1 means you always need a real symbol to start a winning line from the left, but having them across the other four reels gives solid coverage.
RTP and Volatility
Reel Rush has an RTP of 96.96%, which sits comfortably above the industry average. The volatility is rated 5.9 out of 10, placing it squarely in medium territory. You will see regular small wins from the base game thanks to that 28% hit rate, while the expanding re-spins and free spins provide the route to larger payouts.
The maximum win of 1,000x your stake is modest by modern standards, but it fits the game's design. This is not a slot built around chasing a massive single hit - it's about the escalating excitement of watching those reels grow. The re-spin mechanic gives each session a rhythm: small wins, occasional expansion chains, and the rare full-grid free spins round where everything comes together.
For a 2013 release, the expanding reel concept was ahead of its time. Plenty of later slots borrowed the idea of growing grids and increasing ways, but Reel Rush still holds up because the core mechanic is so cleanly executed. The 45-to-3,125 progression gives you something to build toward on every spin.
