Bone Raiders

Bone Raiders comes from Relax Gaming and sits somewhere between a straightforward online slot and a video game homage — the title vaguely nods toward tomb-raiding adventure, and the design carries a cute, almost collectible-toy aesthetic that's become something of a house style for this studio.

A view from above

Players look down on the action as though riding on the back of a winged creature, taking in a grid framed by a moat, ancient walls, and dry, cracked earth. It's a look that shares clear DNA with other Relax Gaming releases like Snake Arena and Marching Legions. Trigger the bonus round, and the camera shifts to a more enclosed, stone-encrusted setting populated by amiable skeleton characters — everything here is designed with charm rather than horror in mind.

Two grids, two moods

Bone Raiders draws a clear line between its base game and bonus round. The main game plays out on a 5x3 matrix using a Pay Ways mechanic, where diamonds, clubs, hearts, and spades act as lower-value symbols worth 0.3x the bet for a five-symbol win, while four skeletal character symbols serve as premiums, paying 10x to 100x for a matching five-of-a-kind. There are no wild symbols in the base game — instead, a respin mechanic doubles the win multiplier with every hit, building momentum organically. The bonus round then shifts to a 3x3 grid capable of expanding all the way up to 7x7, introducing a coin accrual system where a multiplying element continues to play a central role.

RTP and volatility

Bone Raiders carries a 96.1% RTP, a touch above the standard market baseline, and is rated medium-high volatility — a fair middle ground that supports both regular action and the potential for larger spikes once the coin-collection bonus gets going.

Max win and stakes

The maximum win sits at 10,000x the bet, and with 243 paylines feeding the base game, stakes run from 10c up to $/€100 per spin, covering a wide range of bankroll sizes comfortably.

Verdict

Bone Raiders blends a respin-driven base game with an expanding, coin-collecting bonus round in a way that feels distinct even within Relax Gaming's own catalogue. The charming skeleton cast helps soften what is, underneath, a genuinely medium-high volatility ride.
