One of the most iconic characters in movie history takes centre stage in Rambo, a 5 reel, 720 ways to win slot from iSoftBet. Featuring Sylvester Stallone as the Vietnam war hero John Rambo, it comes with a bonus feature that offers free spins with expanding symbols as well as a quartet of explosive progressive jackpots. Join the battle from between 50p and £12.50 per spin.

Set against the backdrop of the Vietnamese jungle, the reels in Rambo have a strong military feel – they’re set up in a 3-4-5-4-3 configuration which gives 720 ways to win and feature an assortment of bullets, knives, snakes and Jeeps alongside the lower value playing card symbols. The Rambo logo is the wild, replacing everything apart from the scatter and jackpot symbols.

Rambo himself is the game’s scatter – land 3, 4 or 5 of them anywhere on the reels for a payout of 5, 10 or 15 times your total stake. You’ll also trigger the Free Spins feature and receive 5, 10 or 15 free spins. Before the feature starts, 1 symbol will be chosen at random – this will become the expanding symbol.

When it lands during the feature, it can fill up the entire reel in which it appears. If the scatters hit during the feature, you can trigger even more free spins. The same expanding symbol will be in play for your extras.

The other symbol to keep a special eye on is the hand grenade which is the key to triggering the Explosive progressive jackpot feature. 5 grenades will activate the lowest value Stealth Jackpot. 6 and you’ll get the Bravery Jackpot. 7 and it’s the Honour Jackpot. Land 8 and you’ll scoop the big one, the Explosive Jackpot which awards the biggest prize. You can trigger all 4 progressive jackpots in both the base game and the free spins feature.

Branded content has become something of a speciality for iSoftBet and they certainly know how to make good looking slots. Rambo may not quite reach the heights of the developer’s other film-related titles, such as 24, but it’s still a pretty impressive effort.

There isn’t a huge amount of features on show but the 720 ways to win game engine keeps things ticking over nicely. Throw in the free spins with expanding symbol and the prospect of 4 progressive jackpots and Rambo becomes a playable and potentially explosive slot.
