Introduction
When it comes to longevity in the gaming industry, R Franco could teach its competitors a thing or two. Founded in 1965 by two brothers - Joaquin and Jesus - as a company manufacturing gaming machines, it is now a multinational enterprise working in hospitality, arcades, bingo halls and casinos in addition to online.
This dinosaur themed slot is one of a large range of R Franco free slots available here at Slots Temple. It goes head to head with games such as Pragmatic’s Jurassic Giants slot but has its own features.
Jurassic Slot has a five-reel, four-column grid with 1,024 paylines. The minimum bet size is 0.20 and the maximum is 2.00. There are 11 symbols: the tyrannosaurus rex, brontosaurus, triceratops, stegosaurus, pterodactyl, and the usual playing cards. The scatter is a bowl of dinosaur eggs and the wild is a W preserved in amber.
Theme, graphics and soundtrack
Jurassic Slot is a well-presented game once you get past the welcome screen with its fairly shameless borrowing of the Jurassic Park film logo. The background is a murky prehistoric forest with a large T-rex looming in the center. The reels are semi-opaque, so the background is always in view. The symbols are well-drawn, with intricate details such as the razor-sharp teeth given appropriate prominence. The playing card symbols cleverly incorporate the petrified DNA we remember from the films.
The soundtrack is a slightly strange mixture of comedy music, dinosaur roars and what sounds like giggling children.

Jurassic Slot RTP and variance
Unfortunately, R Franco has not issued any information on the RTP. The variance high.
How to play Jurassic Slot
- Use the plus and minus buttons to either side of the bet level indicator to adjust the bet. Alternatively, you can select the max bet button to go straight to the highest bet level available.

- Click the auto button to enter the autoplay menu, which gives you a choice of automatic spins from 10 to 100. The button displays the number of autospins remaining. Press the button again to exit autoplay.

Jurassic Slot bonus features
Special symbols
The hatching T-rex egg is a special symbol that acts to transform other symbols into T-rex symbols. The hatching egg itself also turns into a T-rex. The largest of the symbols each have a counter that can increase with each spin. Once the counter is full, the symbol will turn into a T-rex symbol. If you collect the 15 special symbols on the final spin, you will be awarded an extra spin.
Scatter
The eggs in a dish are the scatter symbol. If you land three or more of these, you trigger the free spins round.
Free spins
You can earn up to 20 spins with five of a kind. During the free spins round, you can retrigger the free spins and the 2x scatter prize will be added.
Wild
During the free spins, a horizontal reel will appear at the top of the game that matches the positions of the three central reels. Every time the wild lands on one of the central reels, it unlocks the corresponding multiplier on the horizontal reel. This multiplier is applied to the total win for the current spin.
Jurassic Slot review: our verdict
Although this is a smartly illustrated game with some inventive animation, there isn’t much variety in the gameplay. There is potential in the concept but it hasn’t been fully realised. The laboratory door that allows you to buy free spins could have been used as a gateway to a genuine bonus game; instead, you have to make do with free spins and multipliers. This slot is adequate but unexceptional.
