Play Spin-Vention for Free

A high standard of artwork is used through this game, with the 5x4 reel grid set within a round window, surrounded by brass pipework, a globe, a telescope, and other items. Ribbons of electricity run down either side of the reels, powering what we guess is a huge blimp as it floats over a city.

The Steampunk style of the Spin-Vention slot machine carries through to the symbols, with the robot joined by a distinguished pilot/scientist, a young woman, and various mechanical bits and pieces. The machinery includes a bonus reel above the main game. This moves one reel to the left on each spin, awarding a feature whenever a glowing mechanical Energy Box lands in view.

This gorgeous looking sci-fi themed slot machine is the work of High 5 Games. This developer is behind some of the biggest hits, including Secrets of the Forest and Golden Goddess.

The Spin-Vention online slot works in the same way as many others, and you win by matching three or more symbols across a payline, starting from the left reel. You can wager between 0.01 and 5.00 on each line, for overall stakes of 0.20 to 100.00 per spin.

It’s a high volatility slot, so don’t be surprised if the reels spin for a while without a win. Generous payouts make up for this, and over the long term, it pays back at an average of 96%.

This paylines table shows you how many times your line bet you win from each symbol –

The wild does what wilds do best and acts as others if it can then help to complete a winning combination.

You can play Spin-Vention for free, then for real money at the top High 5 Games sites. It comes with the option to spin the reels automatically and works across PCs, Android, iOS, and Windows mobiles.

There’s a second wild symbol in this game, and while the Energy Box, (a sort of glowing cube), doesn’t pay any direct prizes, it not only acts as others, but also unlocks the bonus reel at the top of the game.

Once you collect any wins from a spin, you claim whatever bonus is on the same reel as the box. These include stacked wild symbols that fill whole reels, random wilds spreading across the game, win multipliers of up to 5x, and instant cash awards of up to 100x the stake.

Not all of these features of the Spin-Vention slot machine guarantee a prize, but it’s possible to see more than one box at a time, and when this happens, the features combine.

Land at least one globe and arrow symbol above the Energy Box, and you enter a free games round. Each globe reveals a number of free games, so the total is likely to be greater if you land two or three above the box. With enough retriggers of the feature, it’s possible to see a grand total of 100 free spins play out.

The Spin-Vention online slot also has a prize-picking feature that begins when you see at least one blue and gold globe above the Energy Box. The number of picks is shown on the globes, and your task is to pick cog symbols to reveal win multipliers. If you get more than seven selections, the multipliers rise in value, but look out for exploding mines, as these remove lives.

Similar characters appear in the Fortunium Gold Mega Moolah slot from Microgaming. Stacked mystery symbols and free spins are in the mix, but it also comes with one of the world’s biggest online progressive jackpots.

A whole collection of futuristic Victorians land on the reels of the Cazino Zeppelin slot from Yggdrasil. It’s a five-reel, 20-line game with impressive graphics and has a free spins feature with sticky wild symbols.

This is an outstanding example of the Steampunk style, with detailed character symbols in a well-designed setting. There’s plenty of opportunities to grab some prizes from this futuristic land, especially if more than one Energy Box appears. It’s possible to combine all five bonuses from the reel above the main game. The bonuses move to the bottom during the free spins, as you head down into the depths of the airship, but the features remain.
