HarleCoin slot review
HarleCoin is a Red Tiger slot from June 2021, built on three reels with one row and a single payline, and styled around a harlequin. What makes it different is a paytable that moves: HarleCoins land on symbols and raise their values, and each value stays raised until that symbol next pays. Three scatters on the line trigger up to 25 Boost Spins.

How HarleCoin plays
With only one line, a win needs three matching symbols across the three reels. A panel above the reels shows what each symbol is worth right now as a multiple of your stake. Coins can land on any spin, so even a spin with no win can raise a value for later.
- Symbols: cherries, clovers, stars, bells and 7s, plus a diamond-shaped wild.
- Wild: substitutes for the other paying symbols and is the most valuable symbol in the game.
- HarleCoins: coins that can land on a symbol and raise that symbol’s value in the panel.
- Reset: once a symbol is paid in a win, its value drops back and starts building again.
Boost Spins and the carry-over
Land three scatters on the payline and Boost Spins begin, with up to 25 spins. In this round, paying symbols arrive with HarleCoins attached, pushing their values towards the most each symbol can be worth.
The values built during Boost Spins are not lost when the round ends. They carry over into the base game and stay in the panel until the next win with each symbol claims them, so the effect of the round can last well beyond its final spin.

Frequently asked questions
What is a HarleCoin?
It is a coin that can land on a symbol and raise that symbol’s value in the panel above the reels. The higher value stays until that symbol is part of a paid win.
How do Boost Spins start?
Three scatters have to land on the single payline. The round gives up to 25 spins, and the symbol values it builds carry into the base game.
Is HarleCoin a classic slot?
It looks like one, with fruit-machine symbols on three reels, but the symbol values change as coins land and wins are paid, so the paytable is never fixed.
What is the RTP?
The game’s information panel shows it. RTP can differ between operators and game versions, so check the panel in the version you play.
