Crystal Hot 40 is an online video slot developed by Fazi Interactive. It plays out on 5x3 reels and has 40 betways, medium variance, and an RTP of 96.60 per cent. Amongst the features are a gamble option, scatter symbols and a jackpot.


Crystal Hot 40 is a retro fruit-themed slot from game maker Fazi Interactive. The game is played on 5x3 reels with 40 fixed betways that pay from left to right. The exception is the scatter symbol, which pays as a multiple of the total bet across the reels.

There is a gamble feature in which the player is faced with a downward-facing playing card and must choose the colour to double their winnings. You can collect at any time, with the game ending if you make the wrong choice.

There is also a mystery jackpot. Please note that the RTP does not reflect the jackpot contributions.

There are eight paying symbols, with the scatter being the top payer followed by the lucky 7. This symbol acts as a wild, substituting for all other symbols apart from the scatter. The grapes are the next top scorer, followed by the familiar plum and melon. The lower scoring symbols are the orange, lemon and cherry. 

If this designer’s games appeal to you, there are other examples of Fazi Interactive demo slot games available to play for free here at Slots Temple. If you would like to try another classic fruit slot with higher volatility and a similar RTP, the Jammin Jars slot is a good choice.

Theme, graphics & soundtrack

This slot has a classic fruit machine theme and features all the familiar symbols, including the lucky 7 and a high-value scatter. The symbols sit on a transparent screen, with a three-dimensional background suggesting the entrance to a casino with land-based machines on offer.

The game has a simple dashboard for the player, while the soundtrack features the sound of the reels clicking into place and a classic 60s pop tune marking a winning line.

Crystal Hot 40 review: our verdict 

For fans of the classic fruit machine, this is a great slot. The design is retro and familiar to online and land-based machine players alike. The soundtrack adds to the feel of the game, with a 60s tune chosen to celebrate winning lines.

The designer has added a gamble feature, again simple and retro, to help to increase the chances of maintaining your bankroll and to add a bit of spice when a smaller win appears.

The addition of a jackpot, which is another nod to the old land-based machines, is a great bonus. You can watch it grow on screen and, dependent on your bet, can boost your chance of landing it.
