Cashed in Stone

Cashed in Stone is a prehistoric-themed slot from SG Digital that combines modern mechanics with a Stone Age aesthetic. Set in a rocky world of wild beasts and primitive tools, the game offers two major features — the Big Money Wheel Bonus and a uniquely designed Free Spins progression trail. With a 4,096 ways-to-win layout, a two-tier prize wheel, and a collect-to-trigger free spins system, this slot provides a fresh take on feature build-up mechanics.

While its RTP is below average at 91.95%, the game's novelty lies in its ability to strategically accumulate free spins and risk/reward scenarios via the Money Wheel Bonus.

Cashed in Stone transports players to a comically primitive world, blending Flintstones-style characters with hulking rock symbols, bone tools, and wild animal imagery. The grid is carved into a rocky cliff, with characters shouting from the sidelines, and symbols that bounce with exaggerated weight.

The game’s visual identity is bold and cartoonish, yet functionally clean, making it easy to follow even during busy feature rounds. The audio design complements the aesthetic with drumbeats, caveman grunts, and celebratory chants when bonus features trigger, giving the slot a playful yet immersive vibe.

1. Set your bet size using the standard coin value selector.
2. Press Spin to start the 6-reel grid.
3. Wins are awarded for 3 or more matching symbols on adjacent reels, left to right.
4. Key mechanics: Look for Caveman Scatter Symbols to trigger the Big Money Wheel Bonus. Watch for Free Spins symbols to build progress on the Free Spins Trail.

The game runs on a build-and-trigger model, with strategic choices about when to cash in free spins or wait for better reward tiers.

Big Money Wheel Bonus

Triggered by landing 3 Caveman Scatter Symbols.

How it works:

• A prize wheel spins with values from x1 to x5 (multiplied by your total bet).
• If it stops on a multiplier, it’s added to your winnings and the wheel spins again.
• If it stops on a red X, the bonus ends immediately.
• If it stops on a green arrow, it unlocks the second-tier wheel: This wheel contains x10 to x250 multipliers. Same rules apply — stop on multipliers to keep spinning, stop on red X to end.

This feature is a press-your-luck mechanic where tension builds with every spin.

Free Spins Trail Feature

Unlike traditional free spins, this slot uses a progression trail that builds as you land Free Spins symbols.

• Free Spins symbols push the trail forward one step at a time.
• Activate at any point in the lower or middle section using the green button.
• Once you hit the final (upper) tier, free spins trigger automatically.
• Free Spins use the average of all bet values made while collecting.
• Free spins cannot be retriggered.

This system encourages strategic patience, with players balancing risk and reward before activating their spins.

• Create adjacent symbol combinations across the 4,096 ways to win.

• Focus on: Building the Free Spins trail to reach higher reward tiers. Triggering the Big Money Wheel for escalating multipliers.

• Hold out until the top tier of the Free Spins Trail for 10 spins with 2x2 Wilds.

• Watch your average bet size when progressing the Free Spins trail, as it determines your effective stake during the bonus.

• There is no retriggering in either feature, so maximize each opportunity.
