Enter the US civil war in this dark but slick game from Merkur, the German giant of video slot game developing. Cannon warfare is the name of the game in Cannon Thunder as the reels are blasted with wins in every direction. This five-reel, 20-payline game features free spins and a gamble option, making it a fairly familiar format but fun all the same! Play for money or play for free here at Slots Temple, where you will find a large range of other games from this historic developer. You can also play on your choice of device, including mobile and tablet, which means you can play at home or on the go!

17th-century warfare - 21st-century graphics

The reels are set against a dark background and move with the punchy, strict movements of an army. Tense music combines to create a fairly intense scene. The lower scoring symbols are 9, 10 and J, followed by Q, K and A, and finally four mid-scoring commanders and a fictional US flag with an eagle on it.

Make a bet on the US

We all know who won the US civil war, but here you will need to make a bet on whether YOU win big. Bet between £0.01 and £5.00 per line and then pick either 5, 10 or 20 paylines to activate; alternatively, hit max bet to bet the maximum wager per spin of £100. As with any good slot game, you can choose to autospin for up to 100 spins or take each spin yourself, enabling you to adjust the wager as you go.

Scatter and free spins

Three or more scatter symbols, as depicted by a tray of cannon balls, earns you 10, 15 or 20 free spins for three, four or five scatters respectively. The background changes to a ball of fire and the music becomes even more tense as you take your additional spins. As you play, cannon wilds move in from the right on each row, nudging as they go and maximising wins. Wins during free spins are also multiplied by two. 

Wild symbol

The wild is a cannon and can replace any symbol apart from the scatter. The wild will also pay out when it appears more than three times on a payline.

Gamble feature

After each win, you get the option to gamble it all via two gamble features. Click one of the gamble buttons on the lower right-hand side of the screen. The first is signified by some playing card symbols; in this feature, players take a red/black pick to try to double their wins. The second is the gamble ladder - click on this to either rise or fall on the gamble ladder. You can choose to gamble all or half your win.

Merkur's Cannon Thunder is a smartly-designed historical game with slick graphics and fast-paced gameplay. It is ideal for those fascinated by historical warfare, or indeed for slots fans looking for something a bit different to Egypt- or Luck of the Irish-themed games!
