Space Gems Rockblocks

Mascot Gaming runs a 154-title catalog, and Space Gems Rockblocks is its block-puzzle wing — a six-reel grid where the Rockblocks branding marks the studio's own falling-block mechanic line. Small studio, house-built engine, no licensing bill. Austria posts it at #109, and six Finnish brands carry #867.

The block machinery

Six reels, fixed paylines, gem theming, released 19 December 2024. The paytable peaks at a printed 750× of the bet — a deliberately grounded ceiling that tells you the design intent: frequent structure, not moonshots. Stakes run 0.20 to 50.

Who stacks here

The natural player wants puzzle-adjacent slot texture at moderate cost; the 750× cap filters out ceiling hunters automatically. The 0.20 floor keeps experiments cheap, and fifty at the top is enough to matter without inviting recklessness — a stake band with the same grounded intent as the ceiling.

The gravity bill

The feed-supplied return figure is 94.9% — 1.18 points shy of the 96.08% median across our measured games. That's a real discount to average, held by a single unverified source, with no volatility grade alongside. The modest ceiling doesn't obviously justify the elevated hold; weigh that trade honestly before staking.

About 5.1 per hundred settles house-side across time here. Build your session like a block tower — with a planned top. 18+.
