40 Sevens - Diamond Treasures

Introducing 40 Sevens: Diamond Treasures

Apparat Gaming revives the classic 40 Sevens format with this Diamond Treasures edition, a 5-reel, 4-row slot running on 40 fixed paylines. It keeps the fruit-and-sevens DNA of the original while adding stacked symbols, Diamond wilds, and a side game capable of paying out up to an eye-watering 9,999x on its own. Overall RTP sits at 96.1%, with medium-low volatility and a combined max exposure of 12,000x the stake.

How It Plays

Wins form from left to right across the 40 fixed lines, with the Diamond acting as the wild symbol, substituting for all regular icons and frequently appearing in large stacks for extra impact on line hits. Scatter Stars trigger the Free Games mode, while diamonds collected during any spin — base game or bonus — feed into the separate Diamond Treasures side game running alongside the main action.

Theme and Look

Visually, the game stays loyal to the classic 40 Sevens identity: bold fruit symbols, glowing sevens, and polished reel frames, with the Diamond wilds adding sparkle and Free Games introducing a slightly elevated visual treatment. It's a modernised but recognisably retro presentation rather than a full theme overhaul.

Free Games and Stacked Symbols

Landing three, four or five Star scatters awards 10, 15 or 50 free games respectively. During this round, the Seven symbol becomes an additional wild, and because all symbols appear in oversized stacks throughout the feature, expanded wilds can deliver outsized results compared with the base game.

The Diamond Treasures Side Game

Every diamond that lands, in base or bonus play, gets collected into a treasure chest. Once the chest fills, it unlocks a 4x1 multiplier slot that spins independently to reveal a random reward of up to 9,999x — a genuinely huge side prize sitting outside the main payline structure entirely.

Betting and Max Win

Stakes run from 0.10 to 20 per spin, and between the standard 40-line wins and the Diamond Treasures side game, total exposure can reach 12,000x the bet.

Verdict

For fans of classic sevens-and-fruit slots who want an extra system running in parallel, 40 Sevens: Diamond Treasures adds real depth without abandoning its retro roots. Try the free demo at johnessyslots to see the Diamond Treasures side game build up before playing for real.
