Here's a game with a tale about two unusual brothers. Rex Brothers is an online slot game developed by JDB Gaming with a prehistoric theme. It comes with cartoony graphics that include colorful icons and reels that feature rocks. You can also find prehistoric greenery in the background.

Rex Brothers comes equipped with 3 reels and no classic paylines. You will need four or more identical symbols on the matrix to get a winning combo. This game has just two basic symbols – a blue and a red T-Rex. At the center of the reels, there's a golden reel frame. Comets and meteorites appear on the golden reel at random. When the comet ends up there, it will trigger 5 Ice Age Free Spins. Only the blue T-Rex appears during these spins, and it stays in its place. Wins are boosted with random multipliers. Thanks to the meteorite in the golden reel frame, you will get 5 meteorites free spins. This time, both T-Rexes appear, and they carry random multipliers.
