However, thanks to the work of 888’s in-house slot developers, players are now free to play the Under Construction slot.

Continue reading below to see what else Under Constructions has to offer.

How to Play the Under Construction Slot

Before you can spin the reels on Under Construction, you will need your hard hat and know what game functions can be adjusted before each of your spins which we have highlighted below. With 888 games, it is important to know that all their games have a stake size button, Freaky Fruit Slot is an example of this.

Firstly, Under Construction players should adjust their bet size using the “Coin Value +/-” buttons to set how many coins they wish to bet per spin. Then, if you are short on time, hit the “Max Bet” button to your bet to the maximum amount without having to adjust manually.

Once you have set your desired bet amount, you can click the “Spin” button to initiate the spinning of the reels. However, suppose you are tight for time and do not want to fuss around hitting the spin button whenever you are ready to set the reels in motion. In that case, you can also use the “Auto” button automatically, also seen on the Party Pigs Slot, and spin the reels a set amount of times that you wish them to be turned. 

Under Construction Slot Features

There is nothing out of the ordinary regarding this slot’s design, with Under Construction featuring three rows and five reels. This 888 slot has 25 paylines to win from, and betting starts as low as 3p and finishes at $75 per spin. A progressive jackpot is not on offer with Under Construction, but players can get their hands on the fixed 100x jackpot prize.
