Metal Match

Metal Match takes its pieces from the periodic table. Each tile carries the symbol of a metal, with Na, Mg, Al, Cu and Ge among the examples given, and three or more identical tiles together are cleared for points.

That puts a chemistry coat of paint on a familiar rule. You are reading element symbols rather than shapes, although the instructions also mention matching by kind and colour, so the tiles may be coloured as well. Bigger combos set off what the developer calls explosive reactions, and scores go onto a leaderboard.

Later levels get harder in two stated ways: what the developer describes as the metals mixing faster, and obstacles that start filling the board. Neither the obstacles nor a level count is given. For anyone who has forgotten their school chemistry, Na is sodium and Cu is copper; the matching rule itself is simply about identical tiles.

Look for tiles showing the same metal symbol. Get three or more identical tiles together and they clear, scoring points. Chain larger combos to trigger explosive reactions and bigger scores. As you progress, expect the metals to mix faster and obstacles to appear on the board. Keep your score climbing to move up the leaderboard.

The developer does not list the controls for this game. It runs inside the frame above, so a click or a tap on the game is the place to start.

The tiles are told apart by their metal symbols, so it helps to get quick at reading them before the later levels speed things up. Larger combos are what produce the explosive reactions, so they are worth building when the board offers one. Obstacles arrive as you progress, so use the early boards to settle in.

A match-3 with periodic-table metals on the tiles, in a landscape frame (800 by 600). Combos trigger explosive reactions, and later levels add speed and obstacles. Scores go on a leaderboard. No level count is stated.

Jewel Blaster also builds its scores from combos and chain reactions, and GemMine Match 3 likewise puts your scores on a leaderboard against other players.
