15 Diamonds Slot by Playtech

The number in the title is the target. Collect fifteen diamonds and the Grand pays 1000x your bet, the top of a prize ladder that starts small and climbs in uneven steps. Five diamonds is worth 5x, six is 10x, and the values creep upward until they jump hard near the top: the twelfth diamond hands you the Mini at 50x, the thirteenth the Minor at 100x, the fourteenth the Major at 250x, then the fifteenth clears the whole board for that Grand. Getting there works the way most collection rounds do. Blue faceted diamonds land inside gold frames, lock in place, and each new one buys a fresh set of respins while the counter on the left-hand ladder ticks up one rung at a time.

Everything around that feature is a straight classic fruit machine. Ten fixed lines run across purple plums, red grapes and flaming sevens (the pink seven outpays the red), all glossy and oversized against a hot-pink stage that showers sparkling diamonds behind the reels. The golden five-pointed star is the Wild and the top symbol on the paytable, standing in for every symbol except the diamond that feeds the collection. So the base game and the ladder pull in different directions: one wants stars lined up, the other wants diamonds locked down.

There's a free spins round layered on as well, though the diamond ladder is clearly the draw and the reason to keep going. No buy bonus, no ante bet, so both the collection and the free games have to arrive on their own. That's a slower rhythm than Playtech's cash-collect Origins titles, and the fruit-and-sevens dressing is the point. It's a modern Hold & Win engine wearing the skin of an old pub fruit machine.
