Ox Coin (Wazdan) — slot review for players from United Kingdom

Features and the Final Phase of Ox Coin

This part in Ox Coin is the main content, so let's start with it. In the base phase, only the main reel spins: three service symbols (Extra Life, Ox Bonus, Cash Out) rotate on it, while the mini-reels remain empty. The goal of the base phase is to catch Magic Coin symbols in the corners of the grid. Each coin collected in a corner “activates” three mini-reels clockwise: one is not enough, two activates half the field, four activates the full 25-cell grid and an automatic transition to the final game.

25-cell Grid: How It “Comes Alive”

The field starts almost empty: the only active area is the central main reel, four corners are highlighted, and the other twelve niches around the perimeter are darkened. A Magic Coin can only land in one of the four corners; once it locks there, it stays in place until the end of the round, and the three adjacent niches clockwise light up and start spinning. The more corners with Magic Coins collected, the more active mini-reels there are, and the higher the probability that something will land on them. This is a rare logic for the genre: you don't “trigger a bonus,” but gradually build up the field, step by step expanding the space where payouts can occur. The final game is essentially a reward for the “preparation” completed, not a separate event that occurred by chance.

Ox Bonus — Final Phase on 25 Cells

The launch occurs in two ways: either four Magic Coins are collected in the corners in the base phase, or the Ox Bonus symbol (which is the equivalent of a Scatter) lands on the main reel. Upon entry, the player receives three respins. Each new element that lands on the field resets the respin counter back to three — meaning this phase essentially lasts as long as the grid fills up and there isn't a “drought” of three empty respins in a row. All symbols in the final game stick in their places and do not move until the end of the round — hence the name of the Hold the Jackpot series.

The final phase ends in one of two ways. The first is when the player runs out of respins and Extra Lives, and then the total amount of all sticky coins on the field is paid out. The second is when all 25 cells are filled, and in this case, the Grand Jackpot x2500 of the bet is triggered — the only way to reach the ultimate payout. Intermediate Jackpots (Mini, Minor, and Major) appear as regular symbols and are simply added to the other coins.

Extra Lives — Three Additional Chances

When an Extra Life appears in the base phase or in the final part itself, the Extra Lives counter increases by one — up to a maximum of three. These lives act as a “second wind”: after regular respins have ended, Extra Lives are used. If a new element lands on the field at this moment, the respin counter is not reset — only Extra Lives are used one by one. This mechanic adds a chance to extend the session to a full grid in situations where the main three respins ended one cell away from the Jackpot.

Cash Out — Instant Payout from a Mini-Reel

Cash Out is a separate symbol on the main reel, specific to the series. When it lands, the engine randomly selects one of the mini-reels: if an active game element is currently on it, its denomination is immediately paid out, as if the final part had already ended — without waiting for the entire round. This often allows for a small but guaranteed win to be cashed out when the field is still empty and the trigger is far away.

Magic Coin, Cash Infinity, Mystery, and Collector — Four “Faces” of One System

Within the final grid, four special elements operate, and it's important to understand how they combine. Magic Coin is the main “activator”: in the corners, it activates mini-reels, and in the session itself, it transforms into any other symbol except Cash Infinity. Cash Infinity is a rare, valuable element that can land in both the base phase and within the final part; it sticks to its cell until the end of the round and is worth x5 – x10 of the denomination. Mystery transforms upon reveal into a regular coin or one of three Jackpots (Mini / Minor / Major); if the resulting Jackpot is itself a Mystery, it, in turn, becomes one of the three types. And finally, Collector: appears only when a Magic Coin transforms specifically into it. The Collector scans the entire field, gathers values from all coins and Cash Infinity, and multiplies the total collection by x1 – x20. On a full grid where coins have already landed in the corners, a single Collector can single-handedly push the round towards a Jackpot.

Chance Level — Three Levels of Risk

Chance Level™ is Wazdan's proprietary adjustment, and here it's integrated into a single panel with the base denomination. There are three levels: x2 (denomination doubles, chance of triggering the final phase also doubles), x5 (denomination x5, chance x5), and x10 (denomination x10, chance x12 — a special “bonus” for full investment). Chance Level doesn't directly scale payouts themselves: the coefficients for elements remain the same, but since the base denomination increases, winnings in coins appear larger in absolute terms.

Buy Feature — Purchasing Ox Bonus

Wazdan has included a full Buy Feature in Ox Coin. The button immediately opens the final part, without the need to wait for four Magic Coins in the corners or a Scatter on the main reel. The cost of purchase is fixed relative to the current denomination and significantly outweighs the “average” cycle of the base phase, so the Buy Feature is not a “cheap shortcut,” but a way to play only the final phase. At Chance Level x10, the purchase is also multiplied by ten — this is the most expressive mode of the release.

Volatility Levels™ and Ultra Fast Mode — Session Settings

In addition to the math itself, Ox Coin has Wazdan's standard set of “superstructures.” Volatility Levels™ allows you to choose one of the available volatility levels — low, medium, or high: payout statistics shift, but the mathematical expectation remains at the same RTP. Ultra Fast Mode compresses animations to a minimum and reduces intervals between spins almost to zero — useful when playing at a high Chance Level and wanting to get through the base phase faster.

How Final Game Scenarios Unfold

Several typical patterns for how the final phase usually plays out. The first is a “cold start”: Magic Coin activated two or three corners, with one or two coins with x1 – x2 denominations on the grid, respins quickly dwindle, and Extra Lives haven't accumulated. The result is a payout of 5x – 15x of the denomination, not covering the session, but also without a significant drawdown. The second is a “medium cycle”: all four corners are collected, 12 – 18 elements have densely landed on the field, including Cash Infinity and one or two Mysteries that revealed into Mini or Minor Jackpots. The result is a payout of 40x – 200x of the denomination; such sessions maintain the player's basic distance. The third is a “Collector cycle”: in the final phase itself, a Magic Coin transforms into a Collector with a x10 – x20 multiplier, on top of 18 – 22 already sticky elements. The result is a payout of 400x – 1500x, still below the cap, but these are the kind of big wins that cover long bonus-free periods. And the fourth, very rare, is the complete filling of all 25 cells and triggering the Grand Jackpot x2500: the goal of the session, but not an everyday outcome.
