Cash Heist Diamond Edition Slot by Genii

The reels sit in a polished oak display case with a sheet of glass between you and the action, and behind that glass you can see the jewellery store the crew is robbing - velvet rope stanchions, lit display cabinets, sconce wall-lights along a marble corridor. The logo arcs across the top in gold and red with a small white diamond between the two words. It's another entry in Genii's Cash Heist line and the most upmarket of them, swapping the bank-vault staging of the original for a Bond Street boutique.

The cast is small but consistent. A masked man in a black suit pays top - 1000 coins for five - and the red-haired getaway driver in goggles and a crimson coat sits one rung below at 250. Then come the loot symbols: a Rolex-style diamond watch, a sapphire pendant necklace on a gem-encrusted chain, a stack of gold bars, a pearl-and-ruby ring. The royals are cut from the same cloth, literally - a faceted ruby K, an amethyst J, a citrine Q, all glittering like display-case merchandise. The Scatter is a separate sapphire-blue brilliant, and it only lands on reels 1, 3 and 5, which is why the paytable lists a 3-of-a-kind Scatter pay and nothing higher. Four or five Scatters can't physically occur.

Three of them award 12 free spins, and this is where the game gets specific. Every Wild that lands during the bonus drops into a counter, and every fourth Wild collected pays out an extra batch of free spins with its own multiplier attached. There's a queueing rule: those bonus batches don't fire immediately, they wait until your current allocation runs out and then play in order. There's also a hard cap of three such batches, so the absolute ceiling is 12 base spins plus three Wild-collection awards stacked behind them. You can't retrigger by hitting Scatters again, only by feeding the Wild meter. A separate Random Wild routine can also turn one ordinary symbol into a Wild on any given spin, but only inside the bonus, never in the base game.

Max win is listed as 13,300 coins, which works out to about 133x at the default $1.00 stake. Modest by 2024-era standards, but consistent with how Genii's older series played - the scaling came from feature triggers, not from the base reels. No buy bonus, no jackpot, no ante. Just the Wild meter doing the work.
