Planarity is a simple but addictive puzzle based on a tangled series of connected dots. Untangle the web until none of the connecting lines cross.
Not as easy as it sounds; tho' not as difficult as untangling your daughter's skipping rope (or the chain on your husband's gold medallion ;o)
This Lite version of the game features 3 modes of play and is available on all your iOS devices. All puzzles are auto-generated; so you'll never need to buy another puzzle book (or make any in-app-purchases).
