Some time ago there was a boom of match-3 game in the world of casual gaming, some of them were only commercial. Now one of them appears as a free flash game.
The Treasures of Montezuma 2 offers the right content you want from match-3. Just move the stones so you match the same types in a line. They then disappear and you get point and maybe one of special stones that must be collected. There is a lot of them later making beating the level quite difficult and maybe long.
