WINGO!'s Coin Oink – Hold & Win operates on a 3x3 grid where all payouts come through the Hold and Win bonus rather than traditional paylines. The slot features 96.98% RTP, medium-low volatility, and a maximum multiplier of x2,500. Wagers span $0.10 to $100. A vibrant purple cosmic backdrop frames the deep red playing field, styled with gold-bordered coin symbols and three cartoonish piggy bank characters displayed above the grid in green, pink, and blue.
The bonus triggers when three coin symbols appear on the central horizontal reel. Coins lock into their positions, and 3 spins are awarded that reset with each new landing and decrease by one on empty spins. Standard coins hold values of 1x to 4x, and Sticky Coins at 5x to 9x carry over from the base game into the bonus when it activates. All locked coin values are summed at the end of the round for the total payout.
Each piggy character can activate randomly when the bonus begins. The green piggy (Save) adds 3 spins when the counter reaches zero. The pink piggy (X-Shoot) applies a 1x to 8x multiplier to a coin during final calculation. The blue piggy (Extend) expands the field to 3x5, creating additional locking positions and enabling the Royal Jackpot. Mystery Symbols and Mystery Jackpot symbols reveal their values when the round concludes.
Five jackpots are available: Mini, Minor, Major, Grand for filling the 3x3 grid, and Royal for completing the 3x5 expanded field. A Collect symbol gathers all visible values into one payout. Three Buy Bonus tiers offer direct entry with varying piggy activation and multiplier frequency. Coin Oink – Hold & Win builds its gameplay loop around the interaction between locked coins, piggy features, and jackpot progression.
