Затерянный город - Три в ряд

"Затерянный город - Три в ряд" is a browser puzzle where you align stones in rows to uncover ancient ruins. The standout feature here is "depth filtering": after every match, a layer of dust vanishes to reveal tiles underneath instead of just dropping new ones from the top. You work with what is already on the board rather than an endless stream of new pieces.

Gameplay relies on mouse clicks: you click one stone, then an adjacent one to swap their positions. The goal of each turn is to match three or more identical items in a horizontal or vertical line. Once a row forms, the items vanish and upper stones fall down to fill the gaps. You have to think ahead constantly, since one move might accidentally trigger a chain reaction that is not always helpful. The player decides exactly where to make a swap to clear a path toward locked tiles on the field.

This is a solid choice for anyone who wants to click stones and zone out for half an hour without stress. There are no timers pressuring you, so you can plan your moves calmly. Tip: focus your moves on clearing the very bottom rows first, as that is usually where the cascade starts. If you leave rubble at the bottom, upper elements will just block the swaps you need. Better to clear the foundation immediately than to try and dig your way out later.
