Joker Bombs slot review

Joker Bombs slot facts

Hacksaw Gaming launched in 2018, is headquartered in Malta and has been listed on Nasdaq Stockholm since June 2025. It holds a Gambling Commission licence and is best known for Wanted Dead or a Wild. Joker Bombs, from December 2021, is a lighter-hearted game: a joker theme, a pay-anywhere grid and bombs that multiply wins. See our Hacksaw Gaming slots page for the studio and the slots hub for more reviews.

These numbers follow the developer’s published figures as listed on Slotcatalog’s Joker Bombs page (opens in a new tab). Check the help screen for the RTP your casino runs.

How the features work in Joker Bombs

Pay anywhere

There are no paylines and no need for symbols to touch. If eight or more of the same symbol appear anywhere on the 30 positions, they pay. The more matching symbols, the higher the payout band, as the paytable shows.

Tumbles

After a win, the winning symbols disappear and new ones fall into the gaps. If the new arrivals create another set of eight or more, that pays as well, and the sequence continues until no win remains. Our page on cascading reels explains the mechanic.

Multiplier bombs

Multiplier bombs can land on the grid, each carrying a value. During a tumble sequence their values combine, and the result is applied to the wins from that sequence. The help screen lists the possible bomb values and exactly how they are combined.

Ten free spins

Three or more joker scatters trigger 10 free spins. In the round, bombs appear more often than in the base game, which is where the larger multiplied results tend to come from. Our free spins feature guide explains how this is priced into a game.

How Joker Bombs’ pay-anywhere grid compares

Slots use four main systems for deciding what counts as a win. Joker Bombs uses the loosest one: position doesn’t matter at all.

Pay-anywhere games tend to produce wins built from many low-value symbols, then rely on tumbles and multipliers for bigger results. The RTP stays at 96.48% whichever system a game uses, because the pay values are balanced to fit. Our ways to win guide goes deeper.

What Hacksaw’s 3 of 5 volatility means for Joker Bombs

Hacksaw rates its games on a scale of 1 to 5, and Joker Bombs sits at 3: medium. Many Hacksaw titles, such as Chaos Crew and Hand of Anubis, are rated 5 of 5. A medium rating means the return is spread more evenly between frequent smaller wins and the bigger multiplied results in the bonus.

The 5,000x cap fits that profile. It is half the 10,000x of several high-volatility Hacksaw games, which leaves more of the 96.48% return available for everyday wins. For a player, that usually means smoother sessions and a budget that lasts longer, without any change in the long-run cost. Our volatility explainer has the detail.

Multiplier bombs in a tumble: a worked example

This example uses made-up values at a 50p stake to show the arithmetic. The game sets the real bomb values.

1. A spin pays 40p from nine matching symbols. A bomb lands on the grid.
2. The symbols tumble and a second win pays 60p. Another bomb lands.
3. A third tumble pays 50p, and then no further win forms. The sequence wins total £1.50.
4. Suppose the two bombs combine to 6x. The sequence pays £1.50 × 6 = £9.
5. Without the bombs, the same spin would have paid £1.50, three times the stake.

Bombs matter most when they land in a long tumble sequence with several wins to multiply. In free spins, bombs land more often, which is why the round carries much of the game’s upside. For the general maths, see our multipliers guide.

Joker Bombs RTP: what 96.48% costs

The house edge is 100% minus the RTP, here 3.52%, and the average cost is total stakes multiplied by that edge. One spin every 2.5 seconds is the fastest pace UK rules allow, so 1,440 spins is the most you could play in an hour. A house edge calculator lets you test other stakes, and small RTP differences matter less than stake size and pace.

What £20 buys on the Joker Bombs slot

Medium volatility gives a £20 budget a reasonable chance of lasting through a decent number of spins at 10p or 20p, although no session is predictable. At £1 a spin, 20 spins is a short window for three scatters to land. Choosing a stake that gives you at least a couple of hundred spins is a sensible way to see what the game does. Our guide to making a budget last has more ideas.

Joker Bombs max win: 5,000x in context

The cap is 5,000x your stake: £500 at 10p, £5,000 at £1, £10,000 at the £2 UK limit for 18–24-year-olds and £25,000 at the £5 limit for those aged 25 and over. That matches Pragmatic Play’s pay-anywhere game Gates of Olympus at 5,000x and sits well below Hacksaw’s own Wanted Dead or a Wild at 12,500x.

Reaching it would need a long tumble sequence with high-value bombs, most likely in free spins. The RTP already includes that tiny chance. For what happens when a cap is hit, read max win caps explained.

How to play Joker Bombs online

1. Register with a UK-licensed casino and pass age and identity checks; demo play also needs age verification.
2. Open Joker Bombs and read the help screen for the RTP, the bomb values and how they combine.
3. Choose a stake within the UK caps: £5 a spin at 25 or over, £2 at 18–24.
4. Spin manually. Eight or more matching symbols anywhere pay, then tumble away.
5. Watch for bombs during a tumble sequence and three or more joker scatters for 10 free spins.
6. Keep an eye on the net spend and time display and stop at your planned limit.

Joker Bombs and UK slot rules

Joker Bombs must meet the Gambling Commission’s rules for online slots in Great Britain. The Commission’s online slots stake limit guidance (opens in a new tab) caps stakes at £5 per spin for players aged 25 and over and £2 for those aged 18–24. Under RTS 14 (opens in a new tab), each spin must last at least 2.5 seconds, turbo and slam-stop are banned, and the game can’t celebrate a return that is no more than the stake. Autoplay isn’t allowed.

Some slots sold in other markets include a bonus buy. Since a Gambling Commission warning in January 2020, feature buy-ins are not offered to British players, so in the UK the free spins come only from landing the joker scatters. Our feature buy rules page explains the background.
