Our friends at Ordnance Survey thought we were in need of a little geo-fun and have a map symbol game for you to try out.
To play Map Symbol Slide, you simply swap one map symbol with an adjacent one to create a line of three or more identical symbols horizontally or vertically. As symbols disappear, new symbols will slide down to fill their space.
The game is over when no more moves can be made.
Let them know how you get on and post your high scores on the OS blog.
