Join a gang of cartoon martial artists in 5 Ninjas, a 5 reel, 25 payline slot powered by Eyecon. This action adventure comes with wilds that double payouts, 10 free spins with all payouts trebled plus a pair of pick’em rounds where each selection can award a payout of up to 200 times your stake. Play from between 25p and £12.50 per spin.

We’ve often been a little disappointed by the design of slots from Eyecon but 5 Ninjas is a cracker – a Japanese temple forms the backdrop to the reels which include the 5 Ninjas of the game’s title alongside nunchucks, daggers and knives.

The sword is the top paying symbol – land 2, 3, 4 or 5 of these and you’ll pocket 1, 25, 500 or 5,000 coins. The lit fuse is the wild – it can land on reels 2 and 4 only. When a wild forms part of a winning combination, that payout is doubled.

Unusually, there are 5 scatter symbols – each 1 represents earth, wind, fire, water and metal. When they land, they light the meter above that reel. That meter will stay lit for the 5 spins that follow. If you manage to light all 5 meters at the same time, you’ll trigger the Secret Ninja Multiround Prize Pick feature.

You’ll then be shown a selection of doors – pick 1 and hopefully release a Ninja and in the process, win a cash prize worth up to 200 times your bet. Keep on picking until all the Ninjas are free or they’ve been captured by the guards.

There’s a second picks bonus, the Bonus feature, on offer in 5 Ninjas. This one is triggered at random and can hit on any base game spin. Pick 3 of the money pouches shown – prizes of up to 100 times your stake are on offer here.

Rounding things out is the Free Games feature which is triggered by landing 3 coin scatters on the same spin. You’ll then be awarded 10 free spins with all payouts trebled. The Ninjas will face an animated opponent under the reels during the free spins – if they’re victorious 10 times during the feature, you’ll get another set of free spins. You can retrigger up to 15 times giving you up to 160 free spins in total.

5 Ninjas is a feisty little slot as the variance here is high. The features aren’t the easiest to trigger but offer some good winning potential. Just expect plenty of lean spells along the way. You can win up to 400 times your stake on each spin though. The design here is a step up from many Eyecon-powered slots. They have kept their usual impressive features intact though which is a big plus.

The extremely high volatility means this won’t be a slot for the faint of heart or short of bankroll. If you can cope with the potentially big swings, there’s some top entertainment on offer from the 5 Ninjas. If you like the theme, Red Dragon Wild by iSoftBet is recommended.
