Diamonds Up Slot Information
I saw a vibrant blue and purple backdrop with circles and a cheap and cheerful tune, while the reels sit centre with a pink Symbol Upgrade Ladder on the right. Wins pay left to right from reel one on 25 paylines, and you need at least 3 matching symbols. It runs smoothly on mobile, tablet, and desktop. The counter above the reels shows a 1 to 30 cycle, which frames the pacing and gives you a clear sense of where upgrades might land.
The lower-paying set is fruit: watermelons, grapes, oranges, plums, and cherries, each paying 2x for five of a kind. Higher-paying symbols are bars, horseshoes, bells, and 7s, which go from 4x up to 40x for five. Diamond Wilds land on reels 2, 3, and 4, substituting all regular pays. Scatters can land anywhere to trigger 9, 12, or 20 free spins for 3, 4, or 5, and they also pay 5x, 20x, or 100x on the trigger.

Diamonds Up Slot Features
In Diamonds Up, Diamond Wilds act as progression symbols on the Symbol Upgrade Ladder. Each spin belongs to a 1 to 30 cycle shown by the counter. Every Diamond Wild fills one step; each level has three steps. When a level is completed, all current lower-paying symbols are upgraded to the just-filled symbol. Upgrades apply before win evaluation and persist through the cycle. When spin 30 finishes, the ladder resets and symbols revert, starting the next cycle from a clean slate.
Free spins arrive when 3, 4, or 5 scatters land, awarding 9, 12, or 20 spins. All upgrade progress remains active in the round, and Diamond Wilds keep pushing the ladder as they do in the base game. The bonus can retrigger with more scatters. When the free spins end, the state you reached on the ladder transfers to the base game, so your 30-spin cycle continues from where it paused, which can set up tasty screens packed with higher-paying symbols.
Feature Buy offers four starting positions on the ladder. Pay 20x, 120x, 200x, or 800x the bet to trigger free spins with the second, third, fourth, or fifth level already filled. After the bonus, the saved base game state returns. I used the cheaper buy to test pacing and the top one to chase near-full screens; the spread felt fair for a game capped at 20,000x, given the high volatility and small top stake.
