Android match-3 · lightning jewel mechanic
Line up four gems in a row and most match-3 engines hand you a lightning jewel: swap it into any spot and it clears the whole row or column it lands on. The exact trigger, and what a five-gem shape does instead, differs from game to game — this page walks through four titles on Google Play that use the mechanic.
The lightning jewel is a special piece created when the player matches four gems of the same colour in a straight line, instead of the usual three. Once it exists on the board, swapping it with a neighbouring gem — any colour, any type — sets it off. The effect clears every gem along its row or its column, not both, and the direction is usually fixed by how the match-four was oriented when the piece was formed.
Some titles split the reward by shape rather than just count. In Jewels Magic: Mystery Match 3, a four-in-a-row still makes the lightning jewel, but arranging five gems into an L shape produces a separate piece, the Jewel Bomb, which clears a block around it instead of a full line. The other three games in this comparison keep it simpler: four in a row is the only route to a lightning jewel, and there is no separate bomb piece.
Four-in-a-row rarely happens by accident once a board fills up with mixed colours, so it helps to plan for it a couple of moves ahead rather than hope for it.
Same core idea, four different implementations. This is what each game on Google Play does with it, as of the listing checked below.

Clearing a row or column with a lightning jewel usually drops the pieces above it downward, which can chain into further matches without any extra input — the genre convention behind most match-3 engines, these four included. A row clear that happens to line up three of the same colour on the way down keeps going without spending another move.
The bigger payoff in this style of game is combining two special pieces on the same swap. Pairing two lightning jewels together typically clears both a full row and a full column at once, centred on the swap point, rather than just one line. It costs the same single move as any other swap, so it is worth deliberately parking a second lightning jewel next to the first instead of using it immediately.
Cool Cat Game
A straightforward jewel-swap board spread across a level map, with stars earned per stage. Matching four in a line creates the lightning piece; there is no separate bomb or rocket variant, so the row clear is the only special effect on the board.
