Jurassic Juniors Slot
Line up five Eggs in Jurassic Juniors, and the scatter pays 450x. Line up five Big Mommas, the top symbol on a 25-line pay screen, and you get 380x. Eyecon has built a dinosaur nursery where the symbol that never needs a payline outpays the one at the head of the paytable, and where two Eggs are already worth collecting. That inversion shapes the whole demo, from the scatter’s two-symbol tier to a free games round that triples every prize it touches.
What’s in the Demo
Fifteen Games, Everything Tripled
Every prize triples during the free games. Not the line wins on their own, but the scatter pays too, and anything the substitute helps build. Three or more Eggs anywhere on the reels open the round, and you get 15 games for it, however many Eggs brought you there. That flat count is the odd part, because this studio usually hands out 15, 20, or 25 depending on how many scatters land. Jurassic Juniors scales the pays instead of the spins.
The round runs on the 25 lines and the wager you triggered it with, and it can be retriggered up to 15 times, so a fresh trio of Eggs inside the round puts the counter back to 15. There’s no bonus round hiding behind it either. Eyecon built plenty of these classics with a second scatter and a pick screen on top, and this one puts everything it has on the one feature.
Big Momma’s Double
Big Momma is the green dinosaur in curlers. She deputises for the rest of the cast, though never for an Egg, and any line she completes pays double. Do it inside the free games, and both multipliers apply to the same win, so a line she finishes there returns six times what the table gives it. That matters before you judge the pay screen, because the values on the help screen are the unmultiplied ones. She pays on her own as well. Five across a line is the 380x top, four is 80x, three is 8x, and two is 0.4x. No other dinosaur here gets near that top rung. Her pair pay deserves a glance too, because 0.4x is five times what any other dinosaur returns for two, and pairs are the wins you’ll actually see most often.
The Nursery Cast
The art is where the 2017 build shows its age in the friendliest way. Twelve baby dinosaurs, drawn with fat outlines and googly eyes, are on a sandy board framed in rough timber, with a cartoon jungle of vines and palm leaves behind it. A yellow longneck with a white saddle, a blue hatchling still sucking a pacifier, a purple runner, and an orange one dragging a club. None of them looks remotely prehistoric, and that’s the joke; Big Momma in her curlers is the punchline.
There are no playing-card ranks anywhere on these reels, which is unusual for an Eyecon build of this vintage and means every symbol has been drawn for this game. The Egg alone gets a stone surround, which is the game pointing at what you’re meant to watch for. The shell even asks whether you’d like sound on before it lets you spin. If the cartoon treatment appeals, the other dinosaur slots on the site take the subject far more seriously.
How to Play
The Egg’s Own Rules
The Egg is the one symbol Big Momma can’t replace, and it’s the only one that pays without landing on a payline. Two anywhere on the reels give you 2x, three give 5x, four 20x, and five 450x, and the game adds the best of those to whatever the lines have paid. Three is also the trigger, so the smallest scatter win you’ll see and the round you actually want are the same event at different sizes.
Everything around it follows the studio’s oldest template. Twenty-five lines pay left to right, each settling at its best combination, with every winning line summed into one payout. Jurassic Juniors uses the same 25-line setup as stablemates like Fluffy in Space, the only change is the size of the ladder rungs.
The line patterns come from a fixed diagram, so a winning shape looks the same on every spin, though you choose how many of the 25 are active. Free games aside, there are no modes and no side bets, just the line count and stake to set.
Gameplay Stakes and RTP
The rules give the return to player as 95.436%. Medium is the studio’s own word for this one, and nothing on the pay screen argues with it, so this review keeps the same tier. Seven symbols pay from just two in view, the Egg among them, so small change arrives often enough that the reels rarely feel dead for long.
What the rating doesn’t tell you is how top-heavy the ladder is. Big Momma’s five pays 380x and the next dinosaur down pays 38x for the same five, a factor of ten with nothing in between, so nearly all the swing you’ll feel is carried by one symbol and one round. Nothing on the reels shows a volatility marker, which is normal for this studio, and the return is the only figure the rules commit to.
Paytable
Read the Egg’s row first, because its five-symbol pay tops everything else on the game. Six line symbols pay from two, Big Momma among them, and the six beneath them start at three. From the orange sitter downwards, five in a row comes to 5x or less.
| Symbol | 2 | 3 | 4 | 5 |
|---|---|---|---|---|
| Big Momma (substitute) | 0.4x | 8x | 80x | 380x |
| Green longneck | 0.08x | 1x | 6x | 38x |
| Blue pacifier hatchling | 0.08x | 1x | 6x | 38x |
| Orange dino | 0.08x | 0.8x | 4x | 18x |
| Purple hatchling | 0.08x | 0.4x | 3x | 10x |
| Purple runner | 0.08x | 0.4x | 3x | 10x |
| Orange sitter | – | 0.4x | 1x | 5x |
| Green standing dino | – | 0.4x | 1x | 5x |
| Blue lying dino | – | 0.2x | 0.8x | 4x |
| Orange club dino | – | 0.2x | 0.8x | 4x |
| Red hatchling | – | 0.2x | 0.6x | 4x |
| Yellow longneck | – | 0.2x | 0.6x | 4x |
The game adds an Egg win to the line wins rather than replacing them.
| Scatter | 2 | 3 | 4 | 5 |
|---|---|---|---|---|
| Egg | 2x | 5x | 20x | 450x |
Ultimate Slots Verdict
Jurassic Juniors is the old Eyecon build with its ladder doubled and a scatter promoted above the top line, which makes the paytable more interesting to read than most of the studio's back catalogue. The round it feeds is plain. Fifteen games, every prize tripled, and nothing else behind them. Medium volatility, a 95.436% return, and a steady drip of small wins keep the demo gentle, so those big rungs stay theoretical unless Big Momma lands where you need her. Good-natured, well drawn, and mathematically ordinary once you look past the two headline numbers.
✓ What We Like
- The Egg scatter pays 450x for a line of five, more than any line on the pay screen
- Two Eggs anywhere already return 2x, so scatters are worth something before they trigger
- Big Momma's double and the round's triple stack, taking a line win to six times its table value
- Twelve hand-drawn hatchlings and not a playing-card rank anywhere, which is rare for a 2017 Eyecon build
- Retriggers run up to 15 deep from a flat 15-game start
✗ What Could Be Better
- One published build at 95.436%, so there is no higher RTP setting to look for
- Fifteen games with no multiplier ladder and no pick round behind them
- The drop from Big Momma's 380x to the next symbol's 38x leaves the middle of the pay screen empty
Detailed Review
Jurassic Juniors Play Review
Fifteen games, and everything inside them pays triple. That’s the feature, all of it. No pick round, no wheel, no second screen, no jackpot waiting behind the free games. Three Eggs, 15 games, triple pays, retriggers up to 15 deep. If you’ve worked through Eyecon’s older titles, you have read that rule set before, and you’re reading it again here.
What’s different is the size of the numbers being tripled. Most of the studio’s 25-line classics stop at 200x for five of the best symbol. This one pays 380x for five Big Mommas and then puts a 450x scatter above her, which makes the Egg the most valuable thing on the reels whether or not it lands on a line. Double a win with the substitute, triple it in the round, and a single line can return six times its table value. On paper, that is the strongest set of numbers in the studio’s older range.
Then, the medium rating reasserts itself. Fifteen games is a short round with no multiplier building inside it, and the flat count means five Eggs buy exactly what three do. The big pays are large because 25 lines feed them, not because the game takes more risk than its stablemates. Between rounds, you’re collecting 0.2x and 0.4x wins off rows of hatchlings, and that is a slow way to wait.
So, it’s a 2017 classic with an unusual pay screen and an ordinary round, and how much that appeals depends on what you want from an Eyecon slot. Free play here is the quick way to see the inversion for yourself. If you want a feature with ideas of its own, the nursery isn’t the place to look for one. What it does have is a paytable that rewards reading, which is more than most 2017 line slots can claim.
