Clem's Gems: AGS Takes You Mining for Stacking Bonuses

Clem's Gems is a mining-themed slot from AGS that swaps the usual single-feature formula for a set of overlapping bonuses that can stack on the same spin. Played on a 5x3 grid with 40 fixed paylines, it pairs a bright, cartoon cavern setting with a high-volatility maths model, so the appeal here is the chance for several reward mechanics to fire together rather than one big headline feature. This page walks through how the game is built, what the features actually do, and the numbers worth knowing before you load the free demo.

Theme and Presentation

The action takes place deep underground, with the reels framed by rocky cavern walls and softly lit by lanterns and the glow of the gems themselves. Clem, the cheerful miner, anchors the theme alongside symbols built around mining gear and a spread of colored gemstones, while lower-value spots are filled by the familiar card royals. It is a polished, lighthearted look that fits AGS's house style, and the presentation keeps the focus on the prizes dropping onto the grid rather than on heavy storytelling.

Grid, Paylines and How Wins Land

Clem's Gems uses a standard 5x3 layout with 40 fixed paylines, so every line is active on each spin. Wins are formed by landing matching symbols on adjacent reels along those lines, reading from the leftmost reel. The fixed-line structure keeps the base game simple to follow, while the extra payout routes come from the game's special features rather than from adjustable line settings.

Stacking Bonus Features

The core hook in Clem's Gems is that its features are designed to combine on a single spin instead of being locked away in separate rounds:

• Diamond Prizes: credit prizes that pay independently of the paylines, so they can add to your return even when no standard line win lands.
• Cart Bonuses: mine-cart awards that can stack together during play to build the value of a spin.
• Symbol Upgrade Feature: upgrades symbols on the grid to boost the payout potential of a spin.
• Wild Gems: wild symbols that substitute for regular paying symbols to help complete combinations.
• Boosted Prizes Feature: adds extra credit prizes and multiplier opportunities to the grid.
• Extra Spins: additional spin opportunities that work alongside the other features to extend a winning sequence.

Because these elements can appear and combine in the same sequence, the bigger results come from several of them lining up at once rather than from a single bonus trigger.

RTP and Volatility

AGS supplies Clem's Gems in more than one RTP configuration, with the published versions sitting at 92.03%, 94.03% and 94.89%; the exact figure you play depends on the operator and jurisdiction, so it is worth checking the specific value in any casino's game info before committing real money. Volatility is rated high, which means winning spins can be less frequent but carry the potential for larger returns, so a bankroll that can absorb quieter stretches suits the game best. You can always verify a game's RTP in the paytable before you play.

Max Win and Betting Range

Betting flexibility is broad, with stakes scaling from a low minimum suited to cautious play up to a high ceiling for bigger bankrolls, so the game accommodates a wide range of players. As with the RTP, the exact bet limits can vary by operator, so confirm the available range in the game's settings.
