Coins'n Diamonds Fortune Slot by 1spin4win

Two symbols run this game, and neither is a gem. The round gold coins stamped "Coins'n Diamonds" each carry a printed cash value, and they only matter in numbers. Land three or more anywhere and their values get added together on top of whatever the spin already paid, then the board locks for the main event.

That trigger drops you into a hold-and-win round where the coins that started it stay put and everything else spins again. Each fresh coin that lands sticks too and resets your respins. The goal is simple and greedy: fill all fifteen positions. Cover the whole board and you take the grand payout on top of every coin value you banked along the way. Two special coins can turn up while you respin, a Mini worth 100x your bet and a Mega worth 1000x, and either one drops its fixed prize straight into the tally.

There's a second way in. Three, four or five scatters hand over 7, 10 or 15 free spins, and 1spin4win's Fortune feature can slam the grid full of coins in one hit for a guaranteed full board, which is exactly the state the bonus round is chasing.

The look is pure Vegas jackpot cabinet. Chunky faceted gems in red, violet, blue and green sit on deep red reels planted over a heap of gold coins and loose diamonds, with lit MEGA and MINI meters glowing above. The red gem is the premium, 500x for five across, though everything here is built to funnel you toward the coins rather than the paytable. If you like jackpot coin-collectors, it lands close to Mystery Coin 243 from the same studio.
