Edge Catalyst

Edge Catalyst is a puzzle game about clearing a grid with elemental beams. Water beats fire, fire beats air, air beats earth, earth beats water. Fire a beam with the element that beats a block, and the whole line clears. Each board gives you a fixed number of beams, so the puzzle is choosing which lines to clear and in what order. 24 campaign boards and 120 stage boards, every one checked to be solvable. Endless mode builds a new board every run and keeps getting harder. The daily challenge gives everyone in the world the same board each day. On stacked boards, clear the top layer to reveal the one beneath. Beams run edge to edge along rows, columns and diagonals. Solve a board in the fewest shots for three stars. Element symbols can be turned on for colorblind players. No timer, no lives. Plays offline, no account required. Contains ads. A one-time purchase removes them.
