Alchemist's Forge

Alchemist's Forge is a sliding merge puzzle in the style of 2048, but themed around alchemy. Swipe in any direction to slide tiles across a 4×4 grid. Two matching elements merge into the next element in the chain — Water becomes Steam, Fire becomes Lava, Air becomes Ice, Earth becomes Dust — and the chain continues through ten steps up to the legendary Philosopher's Stone. Chain multiple merges in a single swipe to earn bonus score. The game ends when no moves remain.

Four basic elements (Water, Fire, Air, Earth) spawn at the start and after each move. Rare elements can appear randomly as bonus spawns. You have up to 3 undos per game. Nine achievements track milestones like creating your first rare element, reaching Crystal or higher, winning in 30 moves, and scoring 5,000 points. Results are saved to a leaderboard. Upgrades let you increase the undo count, raise the rare spawn chance, add a score multiplier, or start with double-score moves active.
