The two boards
Base board (4x3). Four reels, three rows, one to three selectable lines, and a BONUS UP strip padlocked above the reels. The five jackpot values are displayed across the top throughout.
Bonus board (4x6). Twenty-four cells. The bottom three rows are active immediately; the top three start sealed. A vertical GRAND marker runs down each flank of the lower block, and a counter reads progress as x/24.

The symbol set
| Symbol | Where it appears | What it does |
|---|---|---|
| Cash coin | Base and bonus | Carries a fixed cash value, collected at settlement |
| Bonus coin (Mini / Minor / Major) | Bonus | Carries 10x, 20x or 50x the line bet |
| Mystery | Base and bonus | Resolves into a cash value |
| Mystery Jackpot | Bonus | Resolves into one of the fixed tiers |
| Coin Collect | Bonus | Sweeps the values of every active coin on the board |
| REEL UP / Super REEL UP | UP row | Unlocks blocked cells on one reel, or on all four |
| MYSTERY UP / Super MYSTERY UP | UP row | Turns mystery symbols into guaranteed jackpots |
| MULTI UP / Super MULTI UP | UP row | Applies multipliers to coin values |
| COIN UP / Super COIN UP | UP row | Raises the cash values already on the board |
| Extra Life | Bonus | Restores a respin to a round that has run out |
The four UP modifiers come in ordinary and SUPER forms. The ordinary version acts on the single reel it lands above; the SUPER version applies the same effect across all four at once.
The jackpot ladder
Mini 10x, Minor 20x, Major 50x, Grand 500x, Royal 1,000x: five fixed tiers, all quoted against the line bet, not the total spin. The three lower tiers arrive as tagged coins during the bonus. The two upper tiers are structural:
- Grand 500x: for covering the bottom three rows of the bonus board.
- Royal 1,000x: for unlocking and filling all twenty-four cells. 3 Oaks has not published a maximum win, so check the paytable in your casino for how your build settles a full board.
Design notes
The presentation is unusually plain for a modern Hold and Win, and that is an ergonomic choice. A purple base-game field switches to saturated lava red the moment the bonus starts, which makes the state of the round readable at a glance. Coin denominations print large, multipliers sit in small tags, and the ladder stays fixed at the top.
Keep an eye on the UP row. In base play it is a locked ribbon behind four padlocks; inside the bonus it is the busiest part of the screen.
Where the numbers come from
3 Oaks publishes the mechanics but has not published an RTP or a maximum win for this game; the return and stake range come from the certified build each operator installs. Open the info panel in your own lobby; that build governs your session. The RTP page shows how to turn whatever figure you find into a cost per thousand spins.
