Spring Tails is BetSoft’s Year of the Rat slot, released for Chinese New Year 2020 as part of its Red Dragon Series — and yes, this is the BetSoft slot, not the soil-dwelling springtail. We rate the Spring Tails slot as a charming, stripped-back game built around one lucky rodent and some very large multipliers.
It looks modest, a 5×3 grid with just five fixed paylines, but the ceiling is anything but. Stacking Lucky Rat wilds and a clean free-spins round push the top win to a theoretical 300,364x. The free Spring Tails demo is the easy way to test that high-variance promise before staking real money.
How to Play Spring Tails
The Spring Tails slot runs on a 5×3 grid with five fixed paylines that pay from the left. We set a stake from $0.05 to $5 a spin — there are no lines or coin sizes to juggle, just a single bet button. If grid features are new to us, our guide to how multiplier wilds and free spins work covers the basics.
The reels sit in a Chinese mountain village, and the symbols lean into prosperity: bags of rice, peanuts, slices of cheese, ancient coins, pearls and gems. The golden emperor’s headwear is the top symbol, paying up to 5,000x your stake for five on a line.
Two characters matter most — the Lucky Rat, who is the wild, and the Golden Key, which is the scatter. Between them they drive the only two features the game has.
Lucky Rat Multiplier Wilds
The Lucky Rat is the wild, and he only ever scurries onto the three middle reels — two, three and four. BetSoft uses the same middle-reel wild idea in the sticky-wild slot Thai Blossoms. Each rat he leaves behind carries a random multiplier of 3x, 4x or 5x that applies to any win it helps complete.
The clever part is what happens with more than one. Rather than adding together, the rat multipliers multiply each other: a 5x and a 3x on the same line become 15x, and a lucky run of wilds can climb all the way to a 60x total.
On a five-line game, that is where the real damage is done — a single well-stacked spin can dwarf everything the base paylines pay.
Golden Key Free Spins
Collect three Golden Key scatters and the game hands us 12 free spins. On its own that is standard fare, but Spring Tails adds a genuine twist.
For the duration of the round, all of the low-value card symbols — the J, Q, K and A — are stripped out of the reels. We are left spinning a leaner grid where only the higher-paying village symbols can land, which makes each free spin meaningfully more valuable.
The Lucky Rat wilds stay active throughout, so those 60x multipliers can strike on the richer symbol set. The round cannot be retriggered, but a Buy Feature lets us purchase it directly rather than wait for the scatters.
RTP, Volatility and Max Win
Spring Tails returns 95.84%, a shade under the 96% we treat as the modern average, and BetSoft rates it high to very high volatility. A base-game hit rate of around 8.65% tells the real story: wins are infrequent, and the game asks for patience.
What that patience buys is the ceiling. With the 5,000x top symbol and the stacking rat multipliers in play, BetSoft puts the theoretical maximum at 300,364x the stake — a huge number for a slot this simple.
There is no progressive jackpot to chase, so the multiplier wilds and the free spins carry all of the upside between them.
Playing Spring Tails Free in Demo Mode
The free Spring Tails demo runs on practice credits with no download or sign-up. For a high-variance game like this, it is the sensible way in.
In demo mode we can watch the Lucky Rat wilds stack, reach the Golden Key free spins and see how the stripped-back grid behaves — all without risking a bankroll on those long gaps between wins. It plays the same in a mobile browser, and sits among plenty of other free demo slots to compare.

Final Verdict
Spring Tails will not win prizes for innovation — it is a simple five-line slot with two features. But it knows what it is: a low-stakes, high-variance flutter where the Lucky Rat multipliers and the clean free spins can occasionally deliver something special.
It suits patient players and low rollers who enjoy chasing a big multiplier over steady returns. If the Year-of-the-Rat charm appeals, BetSoft’s Enchanted Forest of Fortune scratches a similar itch, and there is more in BetSoft’s slot collection.
