Action Bank slot review

Action Bank slot overview

Action Bank comes from Barcrest, the British studio that began with two staff in 1968, released its first game, Invader, in 1970, and was bought by Scientific Games (now Light & Wonder) in 2011. It's the studio behind Rainbow Riches, and Action Bank keeps things similarly straightforward: a plain 5×3 grid, 20 lines and a pick-style bonus. You can compare it with similar games in our slot reviews.

How the features work in Action Bank

The published feature is a single one, and it's a classic of the genre: a bonus round in which you pick from hidden prizes.

1. Golden Vault symbols land on the reels during a normal paid spin.
2. Enough of them trigger the Big Bank bonus; the paytable states exactly how many and where.
3. The game moves to a separate pick screen, where you choose from hidden options to reveal prizes.
4. Your winnings from the pick are added to your balance and play returns to the base game.

Two things are worth knowing about pick bonuses in general. First, the choice is presentation: the result comes from the game's random number generator, so there's no right or wrong pick. Second, the bonus's value is already counted in the 95.16% RTP, so it isn't extra money on top. Our checked data doesn't give the prize ranges or the number of picks, so read the help screen, or a review such as gambling.com's Action Bank page (opens in a new tab).

Action Bank RTP: what 95.16% costs against other slots

RTP is the long-run share of stakes paid back. At 95.16%, the house keeps 4.84% on average. That's higher than many current slots, and the gap is easiest to see per £100 staked:

The difference won't decide any single session, because results swing far more than a percentage point. Over a lot of play it adds up: someone who puts £1,000 a month through slots would expect to lose about £48.40 at 95.16% and £40 at 96%. Barcrest's games often have RTPs around 94% to 96%, sometimes linked to stake, so check the info screen at your stake level. Our page on RTP vs house edge explains the two sides of the same number.

Medium volatility and a £20 session

Medium volatility means a mix of smaller wins with the bonus delivering bigger ones from time to time. Here's £20 at three stakes:

At 10p the average cost of 300 spins is under £1.50, and medium volatility means most sessions won't stray as far from that as on a high-volatility game. At £1, 300 spins would cost nearly three quarters of the budget on average, and the session may not last that long. Our guide to how long £20 lasts on a slot has more worked examples.

How to play Action Bank

1. Open the help screen: check the RTP at your stake, line pays and how many Golden Vaults start the Big Bank bonus.
2. Decide what this session can cost and set a matching deposit limit.
3. Choose a stake within the UK slot cap (£5 a spin aged 25+, £2 aged 18 to 24).
4. Spin manually; UK slots have no autoplay and need at least 2.5 seconds per spin.
5. If the Big Bank bonus starts, make your picks; results are random whichever you choose.
6. Watch the net position and time shown on screen, and stop at your limit.

Action Bank and UK slot rules

The Gambling Commission's online slots stake limit guidance (opens in a new tab) caps each game cycle at £5 for players aged 25 and over and £2 for those aged 18 to 24. See our slot stake limits page for dates and detail.

RTS 14 (opens in a new tab) rules out turbo and slam-stop, sets a 2.5-second minimum per spin and bans celebrating a return equal to or lower than the stake. That last rule matters in a 20-line game: a small line win that pays less than your total stake won't get fanfare. Our game design rules page covers the full list.

Action Bank myths and mistakes

• Myth: picking the middle vault pays more. Every pick is random; the outcome is set by the game.
• Myth: the bonus is due after a long gap. Spins are independent; see can a slot be due a win.
• Mistake: ignoring RTP because the difference looks tiny. Over hundreds of pounds staked, a lower RTP costs real money.
• Mistake: assuming Barcrest RTPs are fixed. Some vary with stake, so check at the level you play.
