Cool Diamonds II

Cool Diamonds II is a gem-and-treasure slot with an unusual twist: matching symbols pay from either direction along its 10 lines, as long as they sit next to each other. Gold bars, diamond rings and coloured jewels fill a 5x3 grid, and covering the whole screen with a single symbol multiplies its prize by ten – which is how the treasure chest reaches its 25,000-coin top award. Three or more scatters trigger 15 free spins that can be retriggered. Low volatility and a 97.77% RTP keep the ride smooth, with stakes of €0.10 to €10 and a maximum win of €30,000. It suits players who value frequent hits over big swings.

Richly rendered diamonds, rubies and gold set a luxury theme. A soundtrack plays in the background, and the game loads smoothly on mobile and desktop.

The treasure chest is the top regular symbol, paying 2,500 coins for five, with gold bars, a diamond ring, a diamond and coloured jewels below it; the green and red jewels start at 10 coins.

Wagers are set by choosing the active lines and the bet per line, for 1 to 500 coins per spin.

Ten paylines are in play, and a win requires at least three matching symbols side by side on an active line, counted in either direction. Filling every position with one symbol pays that symbol's prize multiplied by 10.

Three, four or five scatters award 15 bonus spins, and the scatter also substitutes for other symbols while the free spins run. Extra scatters during the round add more spins.

After a win, the flashing gamble button opens a card game: guess the colour to double the amount or the suit to quadruple it.
