The Flintstones Slot by Blueprint Gaming

Five Freds. That's the persistent unlock counter sitting at the heart of this slot, and it's the one thing that separates it from every other Blueprint Cash Collect machine on the floor. Each Fred you reveal stays active across spins (and across sessions in real-money mode), so the trail you build up in the base game carries straight into the bonus rounds without resetting. It's the same DNA as Rocky Riches, but stripped down to a tighter 5x3 grid with 10 fixed paylines instead of the larger Megaways-style layout.

The base game runs on the standard Cash Collect pattern. Money Bags land with random cash values printed on them, sometimes with jackpot tags attached, and a Collect symbol on reel 5 sweeps every visible Money Bag into a single payout. The four tiers (Mini, Minor, Major, Mega) are fixed at 10x, 25x, 100x and 2000x your bet, not network progressives, and they only land when their tagged bag gets collected. The Mega at 2000x is the realistic ceiling unless you stack a full screen of high-value bags, which is the path to the 10,000x cap.

Three Bonus Scatters trigger 10 Free Spins, and this is where the two distinct bonus variants kick in. A selection wheel decides which one you enter, with each tied to a different Flintstones scene and a different modifier layer on top of the Cash Collect base. Whatever Freds you've already unlocked stay locked in for the round, which is why grinding the base game has actual strategic weight here rather than just being filler between scatter triggers. A Super Bonus tier exists above the standard free spins, accessed through a rarer trigger condition.

Visually the game leans hard into the Hanna-Barbera license. The reels sit inside a blue wooden frame with the prehistoric prairie behind, dinosaur tails curling at the edges, and the character portraits (Fred, Wilma, Barney, Betty) drawn in the original cel-shaded style. The classic Flintstones theme song plays on the splash and weaves into the win cues. For an officially licensed cartoon branded slot, the audio work is unusually faithful, no generic library swaps.

What's missing? No buy bonus, no ante bet, no Megaways layer. Blueprint kept this one deliberately conventional in shape so the trail mechanic and the dual free-spins paths could carry the differentiation. Whether that's enough depends on how much weight the Flintstones license itself pulls for you.
