Online Pokie 3 Chests Bonus Combo at Mateslots Casino: For Real Money and in Demo

Developed by Evoplay, 3 Chests: Bonus Combo was released in 2023. The slot runs on a 3×3 grid with 5 paylines and carries a medium-to-high volatility rating. Its RTP sits at 95.77%, which is competitive among similar-sized games in this niche. The theme centres on treasure hunting — gold, jewels and locked chests fill the reels. What sets it apart from other titles in its class is the bonus combo mechanic, where landing three chests at once triggers a layered prize pick feature. This adds a decision-based layer to the activity that most grid slots skip entirely. Mateslots Casino is one of the platforms where AU gamblers can find this title ready to play.

How the Bonus Combo Feature Works

The core mechanic that separates this slot from standard 3×3 games is the Bonus Combo round. When three chest icons land on the reels simultaneously, the pick-and-win sequence begins. Each chest hides a multiplier or an instant prize, and the gambler picks one to reveal a reward.

What makes this feature more engaging than a basic free spins round is the stacking potential. If a golden chest icon is among the three, the prize from that pick gets multiplied before it is added to the total win. This can push payouts well above what the base game delivers on its own.

Volatility and Win Potential

1. RTP: 95.77%
2. Volatility: Medium-High
3. Max Win: 5,000× the bet
4. Min Bet: A$0.10
5. Max Bet: A$100
6. Grid: 3×3, 5 paylines

The medium-high volatility means wins do not come on every spin, but when they do land, the amounts tend to be meaningful. For AU gamblers who prefer shorter sessions with occasional big hits, this balance works well. The max win cap of 5,000× the bet is realistic and reachable through the bonus combo chain rather than the base game alone.

Who This Slot Suits Best

This slot at Mateslots suits gamblers who enjoy pick-and-win mechanics over endless free spin rounds. The 3×3 grid keeps the visual layout clean and easy to follow, while the chest-based bonus adds a layer of choice that standard grid games rarely offer.

Players who prefer low-complexity titles — where the grid is small and the rules are few — will find the base game easy to follow within a few spins. At the same time, users who enjoy chasing a bigger reward will find enough depth in the combo mechanic to stay engaged over longer sessions.
