1-Of-A-Kind is a high-volatility slot available at 1Win that abandons the standard multi-reel structure entirely. Instead of five reels and paylines, the game uses a single rotating wheel as its entire play area. That is not a cosmetic difference — it changes how wins are determined, how bonuses trigger, and how the jackpot system progresses. This page explains the mechanics clearly so you know what you are actually playing before you start.
What Is This Slot
1-Of-A-Kind is built around a single centralized wheel set against a spaceship backdrop. Every spin rotates the wheel, and wins occur when a complete symbol lands fully visible on it. There are no paylines, no reel combinations, and no adjacent symbol matching — a symbol either lands whole or it does not count.
The symbol set uses classic slot icons: fruit symbols (bananas, watermelons, cherries, grapes, lemons, oranges, bells) at the lower end, and bar and seven symbols at the higher end. Triple sevens are the peak standard symbol at 40× stake. Payouts for base symbols range from 0.2× to 40× your bet.
The game is high volatility. Most spins return nothing or low-value fruit symbols. The substantial payouts come through the bonus features — particularly the Joker jackpot system, which can reach 10,000× your stake.
How the Game Works
Each spin rotates the central wheel. A complete symbol landing on the wheel pays its base value. After any winning spin, several features can randomly activate before the round closes.
Multiplier Booster — triggers randomly after a win and presents a second wheel with multiplier values up to 25×. The multiplier applies to the base win. This can be followed by an Extra Multiplier Booster, which adds a further multiplier — but the two multipliers add together rather than compound. If a 5× win receives a 10× boost and then a 5× extra boost, the calculation is (5× + 10×) + (5× + 5×), not 5× × 10× × 5×. Understanding this prevents inflated expectations from the feature.
Level-Up — triggers randomly after a win and presents a numbered wheel corresponding to positions in the paytable. If a low-value fruit symbol wins and the Level-Up wheel upgrades it by several positions, the win is recalculated using the higher symbol’s payout. A banana win can become a bar or seven win through this feature.
Diamond Scatter — when the Scatter lands on the wheel, it triggers the Free Games wheel. This secondary wheel determines which of two bonus modes you receive: purple sector awards Fruit Free Games, blue sector awards Respin Free Games.

What Bonus Features Are Available
Fruit Free Games (10 spins) Five symbols are displayed above the wheel at the start. Each time one of those symbols lands during the free games, it is removed from the display. Clearing all five retriggers another 10 spins. This can repeat as long as you keep clearing the display, theoretically extending the feature indefinitely. The mechanic is closer to a collection system than a standard free spins round.
Respin Free Games (5 spins) Landing low-value symbols during this mode awards 1 additional respin per landing. Landing bar or seven symbols awards 3 additional respins. The feature can extend significantly if premium symbols appear early, as each one adds three more chances for further premiums.
Joker Collection — three-stage jackpot This is the game’s signature feature. It operates as a progressive multi-stage collection:
- Stage 1 (Blue Jokers): Collect 3 blue Jokers → Minor Jackpot of 50× stake. Advances to Stage 2.
- Stage 2 (Green Jokers): Collect 3 green Jokers → Medium Jackpot of 500× stake. Advances to Stage 3.
- Stage 3 (Red Jokers): Collect 3 red Jokers → Major Jackpot of 10,000× stake.
Each stage uses its own wheel. The wheels contain Joker symbols but also termination sectors — landing on one ends the feature without completing that stage’s collection. Reaching the Major Jackpot requires completing all three stages without hitting a termination sector, which is the condition that makes 10,000× achievable but rare.

Risk Level and What to Expect
High volatility means this slot is not designed for steady, frequent returns. The base game pays out small amounts from fruit symbols, and most sessions will involve long stretches with minimal returns. The game’s value is concentrated in the bonus features — specifically the Joker jackpot stages and the Multiplier Booster chains.
The maximum theoretical win exceeds 10,000× if the Major Jackpot is achieved alongside a Multiplier Booster activation. In practice, reaching the Major Jackpot requires passing through all three Joker stages without termination, which is a low-probability multi-step process.
This slot suits players who are comfortable with extended low-return sessions in exchange for jackpot potential. It is not suited to players who want consistent small wins or low variance play.

How 1-Of-A-Kind Differs from Other Slots
The single-wheel format is the genuine structural differentiator. Most slots — including other high-volatility titles like Gates of Olympus, 1win Bonanza, or Book of 1win — operate on grids with multiple reels, paylines or cluster pays, and cascading mechanics. 1-Of-A-Kind has none of that. One wheel, one symbol per spin, binary outcome per position.
The practical effect is that each spin feels more isolated. In a cascading slot, a single spin can produce a chain of consecutive wins through falling symbols. In 1-Of-A-Kind, each spin produces exactly one base outcome, with bonus features potentially activating after it. The pacing is different — slower and more deliberate per round.
The Level-Up feature is also uncommon in the slot category. Most slots with upgrades apply them through predetermined expanding symbols or bonus round substitutions. Level-Up applies post-win through a separate wheel that recalculates the just-landed symbol’s value — a mechanic that does not appear in most comparable titles.
The Joker collection system is more similar to a Hold & Win or multi-stage jackpot format than to standard free spins bonus rounds. The three-tier progression with separate wheels per stage is closer in structure to Billion Bonanza’s modifier system than to the expanding symbol mechanics of Book of 1win or Gates of Olympus.
