Jewel Quest

Jewel Quest is a tile matching game developed by IWin.

Jewel Quest  is a "match 3" puzzle played on a grid filled with different tokens, such as diamonds, gold nuggets, coins, and skulls. The player may swap any two adjacent tiles, as long as the swap results in a horizontal or vertical line of three or more matching tokens.

The matched set disappears, allowing tokens to drop into the gaps from above; if more matched sets form as a result, they disappear as well.

Whenever tiles disappear, the background grid positions turn to gold. The player must turn each square on the board to gold in order to finish the level. Failing to do so within the given time limit, or reaching a situation in which no more swaps are possible, costs one life and sends the player back to the start of that level.

As the game advances, new variations are introduced to make gameplay increasingly challenging: irregularly-shaped grids, squares in hard-to-reach places, tokens that must be matched multiple times to clear them from the board, etc.
