Hello Casino has recently added the latest American themed Cash Pump Slot which is a fusion of four classic 3×3 reel slots housed in a classic American fuel pump backgroup.

For slots fans who like the classic themed machines, you are in a for a treat as this machine gives you the ability to play four 3×3 reel slots at once along with special features that interact across all four machines.

The base game is a fairly standard machine with class fruit machine symbols on all the reels, there is however one special wild feature which can activate on the middle reel when a full stack of wilds lands on any of the slots middle reels and get transferred to all the other machines along with a randomly chosen multiplier awarded to wins in the range of 1x up to 4x in the base game.

The main bonus round, however, is when the excitement really starts, triggered by landing 4 scatters (1 on each machine) you are then awarded the free spins bonus round.

During the bonus round you can collect additional scatters which fill up the pump meter, when this is completely filled not only do you earn five more free spins each time but the multipliers are also permanently increased for the remainder of the bonus round, whilst the multipliers start on 1x, 2x, 3x and 4x, they double each time making some unusually high multipliers after just a few fuel pump meters have been filled.

Whilst the regular payout for normal wins aren’t too high if you start to get 20x or higher multipliers these can turn into huge wins very quickly.

The gameplay is fast-paced with regular bonus round triggers, some bonuses will be a disappointment with no multiplier increases but when you do get a good bonus round with lots of re-triggers it becomes incredibly exciting with the huge multipliers in play!
