Key numbers for this game on 300er
Which Dinosaur Pays What on 300er
The Megaways mechanic holds a special place in the world of slot games — and Jurassic Kingdom pairs that mechanic with a dinosaur theme to create a genuinely compelling experience. It's easy to find on 300er Casino, and once you start, it's hard to stop.
In a standard slot, each reel holds a fixed number of symbols, which means the number of possible winning combinations or paylines is fixed too. Megaways changes all that. In Jurassic Kingdom's 6 reels, the number of symbols on each reel can vary with every spin — as few as 2 or as many as 7. Multiply those numbers together and you get up to 117,649 different ways to win. That many winning opportunities on a single bet is exactly what sets Megaways apart.
Jurassic Kingdom uses a tumble, or cascade, mechanic. Whenever a winning combination lands, those symbols disappear and new ones drop in from above. This continues as long as new wins keep forming. With each consecutive cascade, the multiplier also climbs — meaning the last win in a chain can be far bigger than the first.
Watching this feature run at full speed on 300er feels like a mini adventure playing out on screen. With every cascade, the game's animations come alive — symbols rising and falling against a backdrop of dinosaurs and erupting volcanoes.
Landing 3 or more Volcano scatters on the reels triggers the Free Spins round. Three scatters award 10 Free Spins, four award 14, and five award 18. During the Free Spins round, Megaways are locked at their maximum — meaning all 1,17,649 ways are active on every spin. T-Rex Wilds also appear more frequently and stick to the reels, helping build consecutive big combinations.
Additional scatters landing during the Free Spins round add more bonus spins — so there's no fixed end point. With enough luck, the round can extend to 50 or more Free Spins in total.
The standout feature in Jurassic Kingdom is the T-Rex Wild. This symbol doesn't just substitute for others — it can stack across an entire reel. When a full reel turns T-Rex, every position on that reel becomes an active Wild, combining with the Megaways mechanic to unlock massive winning combinations.
This is a high-volatility game, so it suits players who'd rather wait for the occasional big win than collect small, frequent ones. A smart first step is to try it in demo mode at 300er — it's free, and it lets you get a feel for the Megaways rhythm before you play with real money. Once you've played a few rounds, it becomes easier to read when a multiplier is building and when Free Spins might be close.
