Two Money Tree symbols, one on reel 1 and one on reel 5, open a bonus built as two picks in a row: a Red Packet sets how many free spins Spadegaming hands out, up to 20, and a gold coin fixes the multiplier between x2 and x10 for every one of them.
Lucky Koi is a slot that draws its theme from the lucky koi. Created by Spadegaming, it is adapted into a video slot. Other koi-themed slots include The Koi Gate from Habanero and Koi Princess from NetEnt. The slot employs a Golden Lucky Koi wild and pairs it with free spins multipliers and a simplified bonus setup. I played 290 spins at 2.00 credits each, wagering 580.00 credits and winning back 357.60, a session return of 61.7%.
The game is constructed on a 5x3 reel layout with 20 set paylines. Line wins pay for matching symbols on those paylines, and a Double gamble feature is available on wins. It provides an RTP of 97.25% and a max win of 1,000x the stake. My largest single win was 82.00 credits on spin 200, which is 41x the stake, and my balance never rose above the 2,000.00 credits it started with before ending at 1,777.60.
The Golden Lucky Koi functions as the wild symbol. The regular symbols are the Gold Ingot, Lotus Flower, Golden Egg and Ancient Coins, along with A, K, Q and J. It substitutes for all symbols, but not for the scatter or the Money Tree Bonus symbol. The scatter pays anywhere on the reels, returning 5x the total bet for three, 10x for four and 50x for five.
The betting range is broad. Beginning at 0.20 credits per spin, it climbs up to 200. Of my 290 spins, 82 paid something and 46 of those paid less than the stake, while my longest run without a win lasted 13 spins and ended on spin 218.
When Money Tree symbols land on reels 1 and 5 simultaneously, the Money Tree Bonus is activated. The bonus opens with a pick of one of six Red Packets from the money tree, which reveals how many free spins are awarded. It grants up to 20 free spins. I landed that combination only once, on spin 62.
Once started, a gold coin pick assigns a multiplier of x2 to x10 to all free spins wins, and the bonus round can likewise retrigger, without limit. Retriggered spins keep the same multiplier, and in my bonus on spin 62 the gold coin revealed x10 before the free spins paid 15.00 credits, 7.5x the stake, taking my balance from 1,918.80 to 1,931.80.
Our Minty Verdict: Lucky Koi converts a traditional theme into a slot without overburdening its structure, and even if the max win is moderate by present benchmarks, its tiered bonus picks carry most of the weight.
