Diamonds Up is a five-reel slot from Red Tiger Gaming with 25 paylines, high volatility, and an RTP of 95.69%. The game centres on Diamond Wilds, which appear on reels 2, 3 and 4, substitute for paying symbols, and help advance a Symbol Upgrade Ladder. A 30-spin cycle tracks progress, with symbol upgrades applied before line wins are calculated and then reset at the end of the cycle.
The free spins feature is triggered by 3 or more scatter symbols and awards 9, 12, or 20 spins for 3, 4, or 5 scatters. During free spins, symbol upgrades remain active, and additional scatters can retrigger the round. Diamond Wilds continue to move the ladder forward in the bonus, with any progress carrying back into the base game after the feature ends.
A demo version is available for players who want to play for free and practice before playing for real money. The game also includes Feature Buy options that guarantee entry to free spins at different stake multiples, with each purchase starting from a saved game state and a pre-set ladder position.
