Stack 'Em: a fruit machine with a coin-collecting heart
Stack 'Em is Hacksaw Gaming's nod to the classic fruit machine, fronted by bright cherries, bars and sevens, but powered by a modern coin-collection feature and a set of fixed jackpots. It blends nostalgia with the studio's appetite for high variance, so it looks friendly and plays fierce. In our testing it is one of Hacksaw's more accessible titles to grasp, even if the maths keeps the big wins rare. Here is how the coins and jackpots work and what to weigh before you play Stack 'Em.
How Stack 'Em works
The game uses a grid with scatter-style pays, so matching symbols reward you for appearing in enough numbers across the screen rather than on fixed lines. The classic fruit symbols handle the ordinary wins, while special coin symbols drive the headline feature. The base game is brisk and built to deliver those coins and the scatters that open the bonus. It is a clean, readable layout that wears its old-school theme lightly, with the real depth coming from the coin mechanic rather than complicated paylines.
The mechanics and the bonus
The standout feature is the coin collection. Coin symbols carry cash values, and gathering them, especially within the free spins round, is how the larger wins build. Some coins map to fixed jackpot tiers, giving the game defined target prizes on top of the variable multiplier values, so there is a sense of chasing a named top reward as well as a big multiplied result. As with most Hacksaw slots, the base game is a build toward the bonus, where the value concentrates, and the maximum win climbs into the thousands of times your stake at the extreme. Operators often offer a bonus buy to enter the feature directly, which is handy but expensive and best used with restraint.
RTP and volatility
Stack 'Em returns around 96 percent in its standard configuration, the usual Hacksaw figure, with some casinos running lower-RTP versions, so check the in-game number before you spin. Volatility is high. The coin feature can deliver a satisfying haul, but those moments are spaced out by quieter runs, and the jackpots in particular are rare outcomes rather than regular ones. If you want to understand why a defined top prize still comes with a streaky balance, our volatility guide lays out the trade clearly.
How to play Stack 'Em
To play Stack 'Em you set your stake, spin the grid, and aim to collect coins and trigger the free spins where the feature pays best. Because the variance is high, stake sizing is the lever that matters most, and smaller stakes give you more spins to ride out the quiet patches before the coins land. Treat any bonus buy as real money spent rather than a guaranteed win, since the bought round can still pay below its cost. New to coin-collection slots?

Is Stack 'Em worth playing?
Strengths: a charming retro look, an easy-to-follow coin feature, and fixed jackpots that add a clear target on top of the multiplier wins. Weaknesses: high volatility, a base game that pays lightly, and a bonus buy that can encourage overspending. Stack 'Em is a good choice for players who enjoy a classic theme with a modern engine and accept the patient, high-variance design. Check the operator's return, pair it with any suitable free spins or bonus, and keep our responsible gambling habits in mind. For more from the studio, read our Hacksaw Gaming review. 18+.
