Chests of Cai Shen Infinity Slot Review

Pragmatic Play is adding a third chapter to its Chests of Cai Shen series with Chests of Cai Shen Infinity, set to release in October 2026. If you've played Chests of Cai Shen 2, you'll feel right at home here. It's more of a lateral step than a massive overhaul, with the gameplay entirely focused on a Hold-and-Win bonus driven by colored coins and mechanical modifiers.

Here is a breakdown of how it plays, how the features work, and whether those expensive bonus buys are worth the risk.

The base game is pretty straightforward. As you spin, colored coins carrying values up to 30x your bet will land on the reels. These are collected into matching chests at the top of the screen.

The collection itself pays nothing, but every time coins go into a chest, there's a random chance it will trigger the Chest Respin bonus with that chest's modifier attached. (Keep in mind, if a coin doesn't trigger the bonus, it doesn't pay out on its own). When the bonus does hit, the coins that triggered it, along with their specific color modifiers, are carried over into the feature.

Once you're in the bonus, the standard symbols vanish, leaving only blanks and money symbols. You get three respins, and landing any money symbol resets the counter. But what makes this game interesting is how the colored coins shape the round:

• Blue Coin: Adds four multiplier zones to the grid, ranging from 2x up to 100x.
• Green Coin: Gives each respin a chance to upgrade the value of up to three coins.
• Red Coin: Splits the game into two separate 5x3 grids.
• Purple Coin: Gives you four respins instead of three.

The multiplier zones are where the game's real potential hides. However, there's a downside: a zone only applies its multiplier if you fill every single spot inside it. If you can pull it off, the payouts can be insane. For example, the game's jackpots land as regular money symbols. If you manage to land a 150x Major coin inside a completed 100x zone, you instantly hit the game's 15,000x max win. Plus, filling all 15 spots on a grid pays a 5,000x Grand jackpot on top of your coin values.

The game offers two bonus buy options, both heavily focused on those multiplier zones.

For 200x your bet, you get the Blue modifier guaranteed, ensuring at least one 100x zone is on the board. For a hefty 750x your bet, you get the Quad version: all four modifiers active and a 100x zone on both grids.

Because those zones only pay if they are completely filled, buying a bonus feels a bit like chasing a target rather than buying a guaranteed big win. In my playthrough, I bought the 200x feature, which lasted about a dozen spins. Brutally, it left the 100x zone just one symbol short of filling, returning only about a third of my buy-in.

I also tried the 750x buy. Thanks to the four-spin reset, it stretched out to nearly thirty spins, and the Green modifier nicely upgraded plenty of coins. But again, both grids left their 100x zones one blank space short, and the round only returned about a fifth of its cost.

Still, the game can pay well without the heart-stopping 100x zones. I had a natural trigger on two grids that managed to fill the smaller 4x and 5x zones, quadrupling the coins inside for a solid 78x win, and it didn't cost me a premium buy to get it.

As the third game in a yearly series, Infinity holds its own. It keeps the solid 96.50% RTP and the massive 15,000x win cap of its predecessor, while slightly dialing down the volatility from "very high" to just "high" and introducing the fun two-grid modifier.

The biggest point of debate will likely be the cost of its features. The "colored coins triggering different modifiers" mechanic is getting quite popular. For comparison, Evoplay's Tiger of Fortune has a very similar structure and charges just 66x for its all-modifier buy (though with a lower 6,414x max win), while Yggdrasil's 3 Piggies of Bank charges 250x.

Pragmatic asking 750x for their ultimate bonus is definitely a premium price tag. They are clearly banking on the potential of those 100x multiplier zones to justify the cost. If you like high-risk, high-reward chases, the tension of trying to fill that final spot in a 100x zone is undeniably thrilling. The swings are real when the reels don't quite connect.
