Donuts

Donuts Slot Review — Big Time Gaming

Donuts, released by Big Time Gaming on 4 July 2018, plays out on a 4×4 reel grid with 2,401 ways to win rather than fixed paylines. The game pairs that mechanic with a Donut Boxes feature, where box symbols on the reels expand or carry a multiplier into the result, and sets its payout theory at 96.54% RTP with a maximum win of 30,700x the stake. The reel set stays locked at four rows, so variation in a spin comes from which ways connect and which boxes land, not from shifting grid sizes.

Core Gameplay Experience

Donuts sets its reels inside an American roadside diner from the 1950s, built around a jukebox, a desert highway and vintage cars, with coloured donuts standing in for the premium symbols and card ranks from 9 to A filling the lower tier.

Big Time Gaming, the studio behind Donuts, was founded in 2011 and operates out of Australia; its catalogue also includes Chocolates, a sibling dessert-themed release that came before Donuts in the same 4×4 format. Players can browse the rest of the studio’s output through Big Time Gaming’s slot catalogue.

Features and Mechanics

Bonus symbols in Donuts take the form of a gold donut icon that triggers the free spins round once enough of them land on the grid; Search-Casino’s listing of slots with bonus symbols groups other titles that use the same trigger type.

A gold foil wild substitutes for the paying symbols and can carry a multiplier value with it, with multipliers in the base and bonus rounds reaching up to 50x on a single symbol. A separate random multiplier can apply to a winning spin independently of the wild, adding another layer of variance on top of an already high-volatility design.

Donuts’ random reward mechanic takes the form of Donut Boxes: specific box symbols that land on the grid can expand symbols or add a multiplier.

Free spins retrigger without a cap, so a bonus round can keep extending rather than stopping at a fixed number of extra spins.

RTP, Volatility and Payout Model

Donuts returns 96.54% to players over the long run and carries a high-volatility profile. High-volatility play in Donuts usually means wins land less often than on a medium-variance game.

Stakes range from a minimum of 0.05 to a maximum of 10.0 per spin, keeping the bet spread wide enough to size a session against the bankroll a high-volatility game like this calls for.

Donuts shares its ways-to-win mechanic and high-volatility rating with several titles in the same cluster, where RTP figures across the group run from 96.21% to 97.07%. Lil Devil, also built by Big Time Gaming, sits close at 96.43%, a small gap worth about $0.11 per $100 of bets in theory in Donuts’ favour, though Lil Devil adds cascading reels on top of the shared ways-to-win base, a mechanic difference that changes how a single spin can keep paying after the first result. Joan of Arc runs at 96.47%, level with Donuts in practical terms. Trump It Deluxe Epicways, at 96.21%, trails by a small margin of about $0.33 per $100 in theory, and layers a Bonus Buy option and a jackpot onto its own ways-to-win mechanic, a further mechanic difference to weigh before treating the two as equivalent. 9K Yeti sits level with Donuts despite its listed 97%, and Lucha Rumble‘s 97.07% edges ahead by a small margin of roughly $0.53 per $100, again a theoretical figure rather than a guaranteed return. Maximum wins vary more sharply than any of those RTP gaps: Trump It Deluxe Epicways caps at 50,000x and Lil Devil at 40,960x, both above Donuts’ 30,700x, while Joan of Arc’s 3,290x and 9K Yeti’s 9,012x sit below it — a ceiling that matters to a player chasing one large hit, not to how often any of these titles pay out. A player who wants the ways-to-win mechanic is served by Donuts, Joan of Arc, 9K Yeti or Lucha Rumble; one who wants cascading wins on top of it has Lil Devil, and one who wants a jackpot alongside a Bonus Buy option has Trump It Deluxe Epicways.

How to Play Donuts Online

A demo version of Donuts lets players run the Donut Boxes feature and the free spins round without staking real money, which is a direct way to see how often the box symbols appear before committing a bankroll to the high-volatility swings described above. Online casinos carrying Big Time Gaming’s games numbered 121 as of 10 November 2026, with Mond Casino, Betroom24 and CasinoStars among the operators listing the studio’s games. A valid gambling licence and the presence of a demo mode are worth checking before a session, whether browsing the slots category or the wider all slots directory.

Verdict on Donuts

Donuts combines a 4×4 ways-to-win grid with a Donut Boxes mechanic and uncapped free-spin retriggers, set at 96.54% RTP and a 30,700x maximum win inside a high-volatility design. That profile suits players who can tolerate extended stretches without a win; it is less suited to a session built around frequent small wins or a tightly limited bankroll, since high-volatility swings can draw down a small balance quickly before any feature lands.
