Updated: August 28, 2019DonutsDonuts is an online slot by Big Time Gaming released in 2018. As its name suggests, it’s all about doughnuts. The American-themed slot is set out on a desert highway with a large diner selling nothing but doughnuts nearby. It has an RTP of 96.54% and is played on a 4×4 grid. Since it uses the all-ways-win mechanic, there are 256 ways to win during the base game. However, thanks to one of the slot’s special features, the number of ways to win can actually increase to as many as 2,401. Keep reading this Donuts slots review to find out everything the slot has to offer.Symbols and PayoutsThere are no fewer than 13 different symbols that can appear on the reels in Donuts. Of these, 10 are standard symbols, while the remaining three are bonus symbols. The six low paying standard symbols are card ranks of different colours. The other four standard symbols are, of course, doughnuts. The symbols and payouts are listed below: Symbol Payout for 4 Payout for 3 Purple Doughnut 15x 0.4x Red Doughnut 2x 0.2x Blue Doughnut 1x 0.2x Green Doughnut 1x 0.2x A 0.6x K 0.4x Q 0.4x J 0.2x 10 0.2x 9 0.2x In order to win, you simply need to land enough matching symbols on consecutive reels, starting with the leftmost one. Since the slot uses the all-ways-win mechanic, it doesn’t matter what position the symbols are in, so long as they’re on consecutive reels.So to win a payout when playing Donuts, you need to have matching symbols appear on all four reels. You can also win by landing doughnut symbols on reels 1, 2 and 3 in the same spin.Along with the standard symbols, there are three bonus symbols. First of all, there’s the wild symbol, which is represented as a stack of different-coloured doughnuts. This symbol can appear on reels 2 and 4. As usual, the wild substitutes for all of the standard symbols to help you form winning combinations.The Gold Donut symbol is the slot’s scatter. This symbol doesn’t offer any payouts, though it’s linked to the free spins feature, so it’s definitely one to watch out for. Finally, there’s the doughnut box symbol, which can boost your wins and even increase the number of ways you can win.While the Donuts RTP is quite good at 96.54%, be aware that the slot is quite highly volatile. This means that you won’t win that often, but when you do, your winnings should be on the larger side. You may well have to spin the reels lots of times before you land a winning combination. You should take the slot’s volatility into account when deciding how much you want to bet with per spin.Betting ValuesWhen playing Donuts, the betting values range from 5p to £10 per spin. There are over 20 different options you can choose from. To the right of the reels, you’ll see the current betting value listed under ‘Stake’, with two green arrows underneath it. Click on the arrow pointing to the right to increase the betting value and click on the arrow pointing to the left to decrease the value. Once you’re happy with your bet size, simply click the large green play button further down to spin the reels.Like many other online slots, Donuts has an autoplay feature. This lets you play without having to click to spin the reels all the time. Once activated, the game will spin the reels automatically for you. Any wins will be added to your balance and any losses will be deducted from your balance. Should you trigger the free spins feature, the autospins will stop so you can play this feature. When setting up this feature, there are three options available. You can choose how many spins you want the feature to run for (you can stop it at any time). You can also set up a limit on your losses and a limit on your wins.Bonus FeaturesThere are quite a few bonus features that should make gameplay compelling and exciting. You’ll be pleased to learn that there’s a Donuts free spins round. To play this round, you’ll need to land three or four Gold Donut symbols anywhere on the reels. For three symbols, you’ll receive 16 free spins and for four symbols, you’ll get 20 free spins to use. Before the free spins round starts, you’ll get to play a special Bonus Countdown game to determine the value of your multiplier.The Bonus Countdown game is played on a separate grid with 16 individual reels, each one a single row high. There’s a countdown that starts off at 3. The reels are spun and every reel can display either a blank space or a Gold Donut symbol that comes with a multiplier of between 1x and 50x in value. If there’s at least one Gold Donut symbol on the reels, the Countdown will be reset to 3. Free spins start once the Countdown reaches 0, or once Gold Donut symbols land on all 16 reels in the same spin. When free spins, all the multipliers you’ve collected will be added up and applied to your wins.While you’re using free spins, it’s possible to win even more. Simply land two, three or four Gold Donut symbols to win 10, 20 or 30 extra free spins respectively. This bonus feature can be retriggered an indefinite number of times.The other bonus Donuts feature is the Boxes bonus. During the base game, boxes of doughnuts can land on the reels. Whenever a box lands, it will reveal either a wild with a multiplier of 2x to 4x or two to four doughnut symbols. Should the box reveal doughnut symbols, it will increase the number of ways to win, since each doughnut in a box acts as an individual symbol. For example, if a box lands on reel 2 and reveals two doughnuts, that reel will have five symbols on it, not four. The maximum number of ways to win there can be when playing Donuts is 2,401. The only way to get this is if you land doughnut boxes on all four reels and if all four boxes reveal four doughnut symbols.Playing For FreeIf you like the sound of Donuts and want to play for free, there are two ways you can do this. Most online casinos offer demo play, which is where you play games using virtual money and can play as much as you like. With demo play, there’s no real money involved, so while you can’t lose any of your money, you can’t win any actual money either.To play for free and still have a chance of winning real money, you should play using casino bonuses. Most online casinos have a good number of promotions you can take part in. A good example of a promotion is the donuts free spins no deposit offer, which you can claim once you’ve signed up and before you’ve even deposited any money into your casino account. You’ll be rewarded with a small number of free spins; some no deposit bonuses may reward you with bonus money instead.Then there’s the welcome bonus. Practically every online casino has a welcome bonus that rewards you for signing up and making your first deposit. From these promotions, you can receive free spins, bonus money or both. There are even some welcome bonuses that don’t just reward you for your first deposit; they reward you for several deposits after your first.Once you’re all done with a casino’s welcome bonus, you’ll be able to take part in all the other promotions. Keep an eye on the promotions section as not all offers will be around forever. Take advantage of reload bonuses and other special offers. It’s also worth making the most of a casino’s loyalty scheme and VIP club to earn even more free play on Donuts and other slots.StrategiesDonuts is just like other online slots in that winning is all down to luck. There’s no decision-making or skill that you can use to improve your chances of winning. However, there are betting strategies that you can learn to help your gambling budget go further. Since Donuts is a high variance slot with payouts occurring quite rarely, you’ll want to make your budget last longer, so you should, therefore, place smaller bets. Do this and you should see a win or two before your budget runs out.ConclusionBig Time Gaming’s Donuts take you to a roadside diner that serves nothing but doughnuts and plenty of bonuses. This highly volatile slot has the potential to reward you with loads of free spins and a very valuable multiplier if you’re lucky enough that is.
