Remember Knightfall? Block Squad is a zanier, more contemporary and less gruelling variation on the theme from the same developer.

Each level is a block grid containing your avatar (a fiesty schoolgirl, or a glowering bruiser), the level exit and a few collectable items.

Move your avatar around by deleting lines of blocks beneath him/her (more blocks will fall from the top to replace them). You can rotate the level by clicking the arrows to left and right.

You have a limited number of moves to collect items and get to the exit. Erasing smaller numbers of blocks will cost you more moves - clicking just one is worth four moves, for instance, while clicking four is worth one - so try not to do things piecemeal.

If you need to flip coloured squares on the Tube, we really can't recommend iPhone app Pixel highly enough.
