One Coin Review

Wazdan is back with another installment in their top-performing Coin series, but this time they've taken a surprising twist. Instead of piling on more coins like usual, or releasing another special edition, they've stripped things back to the bare minimum with One Coin slot. This unique game features a single reel where massive bonus symbols land partially or fully in view, with only full symbols awarding prizes. You'll encounter regular cash coins, mystery coins worth up to 100x, and jackpot coins paying up to 50x your stake.

The Hold the Jackpot Bonus is the main attraction, as usual, offering not only the aforementioned bonus coins but also a brand new Mystery Multiplier symbol. This lucrative addition can boost your current total bonus win by up to x10 each time it appears. Landing the Grand Jackpot symbol in full view during the feature awards the game's max win of 500x your stake. For eligible players seeking more frequent bonus round triggers, Wazdan's Chance Level feature allows you to increase the hit rate by up to 13 times.

Wazdan - Slot Developer

Wazdan is a multi-award-winning game provider with over 210 titles in their portfolio. Founded in 2011, this industry veteran focuses primarily on video slots, boasting more than 190 releases thus far. Licensed in numerous jurisdictions including the UK, Malta, and several US states, Wazdan is known for their extensive slot series, with each new installment introducing innovative features and unique gameplay to players all over the world.

Slot Theme And Storyline

One Coin Wazdan presents a visually striking theme with its giant single reel set against a cosmic purple-blue backdrop. The golden frame surrounding the grid and the single payline add a touch of elegance, while the jackpots displayed on the right-hand side hint at the riches on offer. A pleasant, upbeat melody creates a relaxed atmosphere, punctuated by distinct spin-stop sounds that mark the conclusion of each round. This minimalist design keeps the focus on the large symbols and the anticipation of the next spin.

One Coin RTP, Volatility, And Max Win

The One Coin RTP of 96.17 % is a bit above the industry average, which, according to our research, hovers around 95-96 %. As is always the case with Wazdan, you can choose your preferred volatility level from 3 different settings; low, standard, or high. The One Coin slot max win is 500x your stake, and the win cap can be cracked from a single spin in the bonus round.

One Coin Rules And Gameplay

You can play with bet levels between €0.2 to €10,000 per spin in the One Coin game, which caters to both penny punters and high rollers, and anything in between. There are no regular pay symbols or paylines in this game, as you win when a single bonus symbol of any kind lands fully in view. The regular bonus symbols look like giant gold coins, awarding between 1x and 5x your stake. There are also different special bonus symbols we’ll take a closer look at below.

One Coin Bonuses And Special Features

Bonus symbols pay both in the base game and in the Hold the Jackpot Bonus, and we’ll give you a complete overview below. However, we’ll start by describing the Chance Levels.

Chance Levels (not UK)

The Chance Levels is an ante bet feature that’s available in certain jurisdictions, and it comes with the following options in the One Coin:

• Chance Level x2 - pay 2x your regular stake to increase the Hold the Jackpot chances by 2x.
• Chance Level x5 - pay 5x your regular stake to increase the Hold the Jackpot chances by 6x.
• Chance Level x10 - pay 10x your regular stake to increase the Hold the Jackpot chances by 13x.

Keep in mind that activating the Chance Levels feature does not affect the symbol values.

Jackpot Bonus Symbols

You can land Mini, Minor, and Major jackpot bonus symbols in the base game and during the Hold the Jackpot bonus round, and these are worth 10x, 20x, or 50x your stake, respectively.

Mystety Symbol

The Mystery symbol can also appear in all stages of the game, awarding a random prize between 1x and 100x your stake.

Hold the Jackpot Bonus

Landing the Hold the Jackpot Bonus Symbol fully in view triggers the bonus round, and you start with 3 free re-spins. The re-spins counter resets to 3 each time you land a bonus symbol of any kind fully in view, and the feature ends if you land 3 consecutive non-winning spins.

All your winnings are collected in the total win counter, and the Hold the Jackpot bonus round comes with 2 special symbols exclusive to this feature:

• Mystery Multiplier Symbol - boosts your current total win by x2 to x10.
• Grand Jackpot Symbol - cracks the game’s 500x win cap, ending the bonus round.

Gamble Feature (not UK)

The gamble feature is an option you get after each win, and you activate it by clicking the x2 icon below the single reel. It’s a simple double-or-nothing card color-guessing game. Select either red or black as the winning color, and you’ll double your winnings if the card reveals the matching color. You can do this up to 7 consecutive times per win, but a single wrong guess means all your winnings are lost.

One Coin Bonus Buy (not UK)

The Bonus Buy menu is available via the shopping cart button below the grid, but only to eligible players. It comes with 5 options in One Coin slot:

• The low volatility Hold the Jackpot Bonus costs 50x your stake.
• The standard volatility Hold the Jackpot Bonus costs 75x your stake.
• The high volatility Hold the Jackpot Bonus costs 100x your stake.
• The extreme volatility Hold the Jackpot Bonus costs 150x your stake.

Strategy And Tips For Winning

It’s our experience that larger wins are most likely to come from the Hold the Jackpot feature, which is something to consider when you choose your One Coin strategy. For shorter sessions, it’s best to go with low volatility, while you can consider high volatility for longer sessions if you have the bankroll for it. The sweet spot is standard volatility, which keeps you afloat while still allowing for the possibility of larger wins during the feature.

The 200 Spins One Coin Online Slot Experience

You get to see some base game spins before we purchase the extreme volatility Hold the Jackpot bonus at 0:29 into the 1:59-minute highlights video. The feature went on for quite a while, and you can see for yourself how much we got away with by hitting the play button below.

9 Coins - is a popular installment in this classic Wazdan series, and it plays out on a 3x3 grid with the Hold the Jackpot bonus as the main attraction.

Review Summary And Verdict

One Coin is a highly unique installment in Wazdan's prevailing series, and it stands out compared to both previous Coin slots and the overall market. The single reel format is a refreshing change of pace, allowing the exquisite detail of the symbol artwork to truly shine. The Mystery Coin, in particular, is a visual treat, offering the chance to win up to 100x your stake in both the base game and the bonus round. The regular bonus coin prizes aren't the highest, but they aren’t that far off from what other Coin series releases offer either.

While the base game offers decent payouts thanks to mystery and jackpot symbols, the main aim is to trigger the Hold the Jackpot Bonus. The innovative Mystery Multiplier symbol, boosting your current total bonus round win by up to x10, means larger payouts are possible even without filling the grid. Overall, One Coin slot offers a balanced experience, with decent to solid payouts being possible in all stages. The 500x win cap is fitting for a charming little game like this, and it’s my experience that the Hold the Jackpot bonus triggers fairly often regardless of volatility level.
