Page updated July 2026
Lions GigaBlox is ReelPlay's African savanna slot, built around the GigaBlox big-symbol mechanic developed by its technology partner. The game runs on a 6-reel, 4-row grid with 40 fixed paylines, and its main hook is the way oversized block symbols can drop into the reels to fill multiple positions at once.
Visually, Lions GigaBlox goes for a fairly traditional savanna look: dry yellow grasslands, tall shade trees, a winding river, and distant mountains under wide skies. It's a well-worn setting for online slots, and ReelPlay hasn't tried to reinvent it, but the artwork itself is handled cleanly. Lower-value symbols are 9-to-A card royals rendered in an African-style font, stepping up to hyena, warthog, meerkat, and lioness symbols, with a wild lion appearing across all reels to substitute for everything else.
The default RTP sits at 96%, right around the midpoint for online slots generally, so players can expect a fair, unremarkable long-run return rather than anything exceptional in either direction. It's a solid, dependable figure rather than a headline one.
ReelPlay has classed Lions GigaBlox as medium-to-high volatility, and the listed hit frequency of 26.6% backs that up — wins land a bit more often than in the game's higher-volatility siblings, without sacrificing too much of the excitement that comes from bigger, less frequent payouts.
The core mechanic combines GigaBlox with tumbling wins (removing winners and dropping in replacements) and a free spins round where a rising multiplier builds as the reels keep tumbling. It's a fairly traditional combination of modern slot mechanics rather than anything groundbreaking, but it's put together competently and gives the game room to build bigger combinations as a session goes on.
The top prize on Lions GigaBlox is set at 8,622x the stake, a respectable but not chart-topping ceiling for a game built around growing symbol blocks. Bets range from 40p up to £26/€26 per spin, an unusual but workable stake interval that covers low to fairly high rollers.
Lions GigaBlox leans on familiar ingredients — a well-worn theme, a proven big-symbol mechanic, and a straightforward tumble-and-multiply free spins round — rather than pushing anything genuinely new. That's not necessarily a knock: the combination works, the hit frequency keeps things ticking over, and 8,622x is a fair reward for the volatility on offer.
