Gem Forge is a line-link puzzle game where you drag across adjacent matching gem tiles on a 5x5 grid. Connect three or more identical gems to clear them and score points. Chain clears quickly to build combo multipliers and boost your score. The forge meter fills as you play, unlocking Bronze, Silver, and Gold stages with bonus effects. Daily challenges offer fresh goals each day, and login streaks reward consistent play with milestone bonuses. Each run lasts 60 seconds.
