With a simple but colorful theme and high opportunities for real winning, our guess is that Flux will be one of the most played machines in UK’s online casino sites in the near future.

Stake, bet and win

In its basic version, Flux fits into the template for most modern video machines. Therefore you match 5 reels and 3 lines, with 15 fixed paylines. However, in the bonus round, you can change the machine layout, but more about this you will read further down. The fact that the bet lines are fixed means that you can not play less than 15. To change your bet select the total bet you want to make. A spin can range from £0.10 and up to £100, just like most other of other Thunderkick online slots.

To win, you will be able to redraw symbol combinations of 3 or more matching symbols in regular order. These will be placed in the base game from the far left and right, along any of the input lines. The most valuable symbol of the game is the yellow crystal. These give winnings of up to £2400 per bet line. The theoretical repayment in the game is 96.20%.

Symbols and Functions

Wild symbol

Wild symbol in Flux is made up of a “W”. Like most video slot machines, wilds replace all symbols with the exception of the bonus symbol. The point with this is of course to improve your winning chances. If you do not have a symbol to win, a wild symbol can be used to complete the combination and deliver the winnings to you. Same wild can also be included in multiple combinations at the same time, the winnings can easily shoot away properly.

Bonus or scatter

This symbol is characterized by a “B”. In the game, it is called a bonus symbol, but in practice it acts as a scatter. In other words, the position on the wheels does not matter for this symbol. 3 or more B’s anywhere on the wheels is enough to activate the bonus game. In this you will be awarded free spins, but you will have to choose how these will work. There are 3 bonus games to choose from:

1) Win in both directions – winnings now pay right from left to right
2) Three extra lines – the wheels are expanded, and you now get a total of 6 lines to play
3) Win in both directions AND three extra lines – a combination of the above variants

Depends on the bonus you choose, you get a variety of free rounds, so it’s important to balance and consider what’s most interesting to you.
