Classic Tertis

Classic Tertis places the familiar tile-matching puzzle in your browser, preserving the central idea of arranging pieces as they fall. The goal is to use the available shapes efficiently and create completed lines, making each placement a small decision about space and timing.

Its classic presentation suits both keyboard play and touch controls, so you can use arrow keys or the on-screen controls on any supported device. The appeal comes from fitting pieces together cleanly: a good arrangement keeps the board manageable, while careless placement leaves less room for future tiles.

Use the keyboard arrow keys or the touch controls to move the pieces.

Position each falling tile so it joins the existing arrangement effectively.

Build complete lines with the tiles and keep the board arranged as play continues.

Switch between keyboard and touch input according to the device you are using.
