Blocks

What to Expect

There’s something almost disarmingly simple about loading up Blocks for the first time. You’re expecting reels, scatter symbols, some elaborate fantasy setting — and instead, Hacksaw Gaming just hands you nine colourful cubes on a 3×3 grid and says, essentially, “right, figure it out.” It’s a bit like opening a parcel expecting a birthday cake and finding a really satisfying Rubik’s cube. Unexpected, but kind of brilliant.

Blocks sits firmly in Hacksaw Gaming’s Dare2Win™ instant win family — a lineup of stripped-back, non-traditional casino experiences that prioritise simplicity over spectacle. The concept is essentially a 3D cluster game, with players tasked with forming clusters of identical colours across the compact 3×3 matrix.

That’s it. No paylines to count, no reels to watch cascade.

Nine individual blocks are arranged randomly over the grid, each block possessing six sides that display one of six colours — and your chosen risk level affects how many matching blocks you need to form a winning cluster, from three at Low risk all the way to five at High. So yes, there’s actually a strategic element here that you don’t often see in instant win territory.

Now, the risk levels are where it gets genuinely interesting.

Blocks offers three levels — Low, Medium, and High — and changing the risk level updates the multiplier values that indicate your expected return for a winning spin.

Crank it up to High, and you’re chasing bigger multipliers but needing more matching blocks to get there. It’s the kind of tension that keeps you hovering over the BET button, which honestly surprised me. I expected to be bored within five minutes, and I wasn’t.

On the numbers side, thing is, Blocks is unusually generous on paper. The max win sits at 5,000x your stake, and the RTP options are remarkable — published at 98%, 97%, 96%, 94%, 92%, and 88%, depending on the casino.

That top-end 98% is genuinely rare in this industry. Worth hunting down a casino that offers the higher setting, because as always with Hacksaw, the setting varies by operator. And the 5,000x ceiling? The win multiplier ranging up to 5,000x depends on colour and number of matching blocks, so the gold blocks — the rarest of the bunch — are what you’re really hoping to cluster.

Visually, it’s clean. Maybe a little too clean for some players. The aesthetic is bold and geometric, which is very on-brand for Hacksaw — the design style is a unique DNA blueprint for all their games, and a Hacksaw Gaming release is immediately recognisable.

I actually liked how tactile the blocks felt on screen, the way they shuffle and re-arrange with a satisfying clunk that makes the whole thing feel physical and real. The colour-coding is sharp enough that you can read the grid at a glance, which matters when you’re playing at pace.

Where I’d push back slightly — and honestly this is the main caveat — is that there’s no bonus round. None. There are no bonus rounds or extra features in the Blocks game, which is by design, to keep it simple and instant.

If you’re the kind of player who lives for a free spins round, a big multiplier build-up in a feature, or that moment when the atmosphere shifts and everything goes electric on screen, Blocks simply won’t scratch that itch. It’s comparatively closer to a scratchcard than to something like Hacksaw’s own Wanted Dead or a Wild, which is a wildly more elaborate experience on a 5×5 grid with multiple bonus modes.

But that’s the whole point, isn’t it? Blocks isn’t trying to be that. The instant win format offers an interesting contrast to the complex slots that dominate the market, and its simplicity is arguably its greatest asset — particularly for shorter playing sessions.

It’s the kind of game you play for ten quick minutes when you want a fast hit of excitement without commitment. If you enjoy fast, no-fuss gameplay with a genuine strategic edge and the kind of RTP that actually treats you fairly, Blocks delivers exactly that. Just don’t go in expecting drama — go in expecting efficiency, and you’ll leave pretty satisfied.
