Symbols in Coin UP

Coin UP features various symbols used to form payouts. These include:

• Sticky Coins — Stay fixed on the reels until the bonus game begins, increasing the chance of triggering it.
• Jackpot Symbols (Mini, Minor, Major, Grand) — Special symbols corresponding to different jackpot levels. Filling all 9 reel positions during the bonus game activates the Grand Jackpot, awarding 500× the stake.
• Collect Symbol — Appears during the bonus round and gathers the values of all visible symbols, adding them to the total win.
• Mystery Symbol — Transforms into random symbols during the bonus game, including jackpot icons, adding surprise and higher win potential.
• Coin UP — Appears in the additional row during the bonus round and increases the values of the coins below. It can also turn sticky coins into mystery jackpot symbols.
• Multi UP — Also appears in the extra row during the bonus, adding multipliers to all symbols on the corresponding reel to boost potential winnings.

Bonus Games

The bonus game starts when three matching symbols appear on the central horizontal row. Sticky Coins remain locked in place until the bonus begins.

The player gets three respins and must collect bonus symbols in the form of shiny coins with various values. Each new coin locks in place and resets the respin counter to three. Coins marked Mini, Minor, or Major Jackpot can also land during the feature. Additional symbols may appear to trigger special functions:

• Mystery Symbol — Can hide unpredictable rewards, including the Secret Jackpot.
• Collect Symbol — Gathers all visible values on the reels into one payout.
• If all 9 positions are filled with bonus symbols, the Grand Jackpot is awarded.

Extra Row and Boosters

Above the main reels is an additional row containing powerful boosters:

• COIN UP — Increases coin values below and can convert regular coins into mystery jackpot symbols.
• MULTI UP — Adds multipliers to the reel below, boosting the potential payout.

Ultra Bonus Game and Bonus Buy

A special meter builds up over time. Once full, it activates the Ultra Bonus Game, where all symbols on the grid come with boosted values.

Players can also purchase bonus access. The standard bonus costs 40× the bet, while the extended version costs 75× the bet.
