Jewel Academy is a level-based match-three: swap adjacent jewels to make lines of three or more, meeting each level's objective within a move limit. Matches of four or five create special jewels that clear far more than an ordinary line.
The objectives vary — score, clearing specific tiles, breaking obstacles — so reading what a level actually wants before your first move is most of the difficulty.
Match four or more at once. The shape of the match determines which special you get, and combining two specials clears far more than either alone.
Yes — most levels give you a fixed number of moves to hit the objective, which is what makes planning matter.
Yes — swipe to swap. Nothing to install.
