777 Coins

777 Coins by Booongo is a classic-style slot with a 3-reel, 3-row layout and 5 paylines. The game centres on gold coin bonus symbols, a collect symbol marked by 777, and jackpot values including Mini, Minor, Major, and Grand. The design uses a retro theme with simple reel mechanics and coin-based features.

The main feature is the Hold & Win bonus round, which starts when a collect symbol lands alongside two bonus symbols. In this mode, players receive three respins on a fresh set of reels, with only bonus and collect symbols appearing. Each new symbol resets the respin counter, while the collect symbol gathers the values shown on the visible coins.

A bonus accum feature also feeds the bonus round: each coin symbol in the base game adds to a meter above the reels, and when it fills, the Hold & Win feature begins. This demo version is available to play for free, allowing players to practice before playing for real money and review how the jackpot collection system works.
