Big Rex is being announced by WMS, as a slot machine that will soon enter the online casino market, after being offered first to clients of the land-based casinos. It’s a dinosaur themed slot machine, one that I’m sure will be getting quite a bit of attention from the online players.

When you look at Big Rex, you will see a 5 reel layout, one which is populated with no less than 50 active lines. Apparently, there are rewards of up to 500x offered, along with free spins, scatters and other cool features.

Betting and Prizes

To place a bet in Big Rex, you need to have all your bases covered, or all 50 paylines in this particular case. You can have a minimum bet of just $0.50 if you want that, with $0.01 used for each active line. You can also go a lot bigger, wagering up to $250 for a spin, where each line would get $5.

The game can apparently offer payouts of up to 500x the line bet, which for a game like this should translate to a reward of up to $2,500 cash. It’s not a huge amount, but with various features at your disposal the RTP is improved significantly and it ends up at around 96%. That would be a decent return on your investment, at least in the very long run and considering how slot machines usually pay.

Big Rex Slot Features

Among the game’s most important and fun features, I would mention the tendency that it has, to offer stacked symbols on its reels. This can end up bringing you multiple wins in a single round, particularly with the 50 active lines on which those symbols can appear.

The Volcano Wilds is the first feature symbol that I would like to discuss, since it’s the one that acts as a replacement and gets you paid even more often. These wilds will also be part of a lot of active lines, thanks to them being so common on the reels. A wild symbol will not be used to replace a scatter, but it will still be fun to get on the reels most of the time, since all the others can take advantage of it.

Moving on to the scatters, those are the symbols that you can use to get the free spins to start up. The game can give you 7, 15 or 40 free spins, in exchange for having 3, 4 or 5 of these scatter symbols. During free spins, the slot will use at least two stacked reels for each round. What this can bring you is a lot of wins at the same time, potentially on all 50 active lines.

Theme & Design

Big Rex has been built with the dinosaurs at its basis, and particularly with the T-Rex for inspiration. It’s hardly an uncommon theme to use in a slot machine, and dinosaurs are part of dozens of different games created for the online market. The visuals are somewhat mixed in quality. On one hand, you will notice some badly designed poker cards, the usual ones that all slots seem to get. On the other, there will also be beautifully crafted symbols, showing you dinosaurs, volcanoes and other images from the prehistoric era.


Big Rex feels like a dated release in some ways, perhaps because it uses a land-based slot machine at its basis. The features also seem average for an online slot machine, since a lot of them are much more exciting.
