Donuts Slot Review — Big Time Gaming

Donuts is a video slot developed by Big Time Gaming, first released on July 4, 2018. The game runs on a 4×4 reel grid with 2,401 ways to win rather than fixed paylines, carries a Return to Player rate of 96.54% and is rated high volatility. Some catalogues list Donuts alongside Relax Gaming’s content network; that reference reflects a distribution partnership through which the game reaches additional operators, not a change of developer — the studio credited with building Donuts remains Big Time Gaming.

Big Time Gaming is an Australian studio founded in 2011 and based in Sydney, now part of the Evolution Gaming group. Its catalog of Big Time Gaming slots runs at 90 casinos in our catalog as of 2026, including operators such as BetLabel and GoldenCrown.

Core Gameplay Experience

Donuts runs on a 4×4 reel grid, a layout that supports 2,401 ways to win instead of a fixed number of paylines; a matching symbol landing anywhere across four adjacent reels counts toward a payout. Minimum and maximum bets sit between €0.05 and €10.00 per spin, a range wide enough for both small-stake exploration and larger stakes on the same base-game structure.

The visual theme leans into a retro American diner: bright yellow and red signage, blue accent tones and rows of glazed donut symbols set a light, food-driven, upbeat presentation rather than a dark or serious atmosphere. The theme sits alongside other food and lifestyle titles grouped under Search-Casino’s Other theme category.

The base game moves at a fast pace, with each spin resolving quickly on standard settings. Once the free-spin round triggers, the rhythm changes: multiplier build-up between spins slows the action and shifts the focus from frequent small returns to the bonus stretch where larger payouts concentrate.

Features and Mechanics

Donuts combines several mechanics rather than relying on a single bonus trigger:

• Wilds — substitute for regular symbols across the 4×4 grid, helping complete ways-to-win combinations.
• Bonus symbols — special reel symbols that trigger the slot’s bonus feature once enough appear across the grid.
• Multiplier and Random multiplier — apply value boosts to a spin’s payout, either through a set multiplier symbol or one assigned at random.
• Free Spins — a separate round awarded once the bonus condition is met, run on the same 2,401-ways structure as the base game.
• Function: random reward — an added layer that can hand out a bonus outcome independent of the standard symbol combinations.
• RTP range — Big Time Gaming publishes Donuts with a confirmed RTP band, with 96.54% used as the reference figure in this review.

RTP, Volatility and Payout Model

Donuts has a 96.54% RTP and high volatility, according to Big Time Gaming’s published specifications. The RTP figure is theoretical, calculated over a very large number of simulated spins, and does not describe what any single session will return.

High volatility in Donuts means the ways-to-win base game can run through extended stretches with only small returns, while the free-spin multiplier round is where larger payouts tend to concentrate. Industry slot trackers report a maximum win figure of 40,000x the stake for Donuts; Big Time Gaming does not publish this ceiling directly in its own materials, so the number is best treated as a cross-checked estimate rather than a confirmed studio figure, unlike the 96.54% RTP, which is a specified value.

How Donuts Compares Within Big Time Gaming

Within Big Time Gaming’s lineup, Donuts sits at the lower end of the reported win multipliers next to Chocolates and Pop, both of which carry higher ceiling figures. Players chasing the largest theoretical multiplier inside the studio’s catalog may look at Pop or Chocolates first, while Donuts remains a comparable pick for the same high-volatility, ways-to-win mechanic at a similar RTP.

How Donuts Compares to Other Ways-to-Win Slots

Donuts carries the highest RTP of this five-slot group at 96.54%, ahead of Wealthy Chicken, Light in the Dark and Temple of Dead. Ted is the only medium-volatility option among these five, which makes it the choice for players who want steadier hit frequency, while the remaining four titles, including Donuts, suit players comfortable with high-volatility swings.

How to Play Donuts Online

Demo mode is the practical way to learn Donuts before wagering real money: a free version reproduces the 2,401-ways base game and the free-spin round at no cost, which is useful given the slot’s high volatility. Search-Casino’s directory of free slot demos carries the demo build alongside other titles.

Big Time Gaming’s catalog runs at 90 casinos in our catalog, including operators such as BetLabel and GoldenCrown; availability, minimum bet limits and currency options can vary by operator, so confirming current terms before depositing is worth doing. Players interested in the bonus round specifically can compare trigger conditions across other free spins slots.

Verdict on Donuts

“Donuts pairs a wide 2,401-ways grid with a high-volatility payout curve, suited to players who accept long dry spells for a shot at the free-spin multiplier stage rather than steady small wins.” — Search-Casino Editorial Team

Donuts is a straightforward, high-volatility ways-to-win release from Big Time Gaming, built around wild and multiplier mechanics rather than a stacked feature set. The 96.54% RTP is a confirmed, published figure, while the 40,000x maximum win circulating in industry trackers should be treated as an estimate rather than an official ceiling. It suits players who bet with a bankroll sized for high volatility and treat the demo mode as the first step before wagering real money; it is not a fit for players who prioritize frequent, smaller returns.
