Linez.CC is a puzzle game, where the player has to line five or more tiles to make them disappear. A tile can be moved between two positions only if there is a clear path between them. After each turn, three more tiles appear, except for the moves that make a line to be cleared.
The goal is to keep the 9x9 field free for as long as possible.
The game features an Easy mode, where the future new tiles are presented as hints on the game field. There is also an Undo option. The player can Undo each move once.
While most of the similar games use colored balls, Linez.CC uses colored labeled tiles, which makes it easier for color-blind users to play the game. This is an app version of the web game, which resides at the same address.
