Release Date 
Developer 3 Coins by 3 Oaks Gaming is a 3x3, five-line slot released in January 2021. The game centres on a Hold & Win bonus, with silver and gold coin bonus symbols forming the main feature. A full stack of bonus symbols on the middle reel activates the round, adding the triggering values to a win meter and starting four respins.
During the bonus round, the middle-reel symbols remain locked while new bonus symbols can land to increase the total. The respin counter resets after each new symbol, giving players more chances to build the meter. Diamond symbols may also appear during the feature, carrying multipliers from x100 to x500.
This page can be used to play for free in the demo version, which allows players to practice before playing for real money. The slot combines classic reel design with a bonus game focused on locked symbols, respins, and high-value multiplier features.
