Heavy industry is not a subject we would normally associate with online slot machines but who cares what the theme is as long as it’s good fun to play; Under Construction is the game in question here and it’s full of hard hats, power tools and steel toe-capped boots – read all about it below.

Under Construction is a five reel slot with three rows and up to twenty five paylines; those reels spin within a frame made of girders while in the background heavy machinery does it’s thing. A workman with a slightly-too-large hat loiters in the left hand corner.

There are just five standard symbols here and they include the hard hat, the pneumatic drill, the handheld drill, a pair of safety boots and a saw/hammer combo.

The wild symbol is some health and safety equipment and it will substitute for all others to help form winning combinations except for the circular saw scatter icon.

Bonus Features

Free Spins

This is triggered by landing three or more of the circular saw scatter symbols anywhere in view for which you will receive ten free spins; before the spins start hit the ‘Stop’ button to reveal which symbol will be the expanding one. If three or more of these symbols appear they will all expand to fill their respective reels.

Gamble Feature

Each base game win can be gambled by clicking the ‘Gamble’ button toward the left of the screen (it won’t work in Autoplay). Pick the boot or the hat to try and double your winnings but get it wrong and you’ll lose it all – there’s a maximum winning streak of ten available.

Verdict

Under Construction makes the most of what could be quite a run-of-the-mill theme and it has an industrial atmosphere which suits the game well; the free spins round seems to offer some big wins so why not check this game out.
