Paper Bridge by Clever Hamster Games brings bridge building games back to its roots, using simple physics and simple mechanics to give gamers a chance to relax their lateral thinking brain and give some air to their literal thinking brain. I'm fairly sure I just made those last two things up, but where games like Tiki Towers may require you to think outside the box, Paper Bridge lets you stick to basic engineering principles to get the job done.

Only three tools are given to draw your bridge: A black pencil for the road; a green pencil for the supports; and an eraser to tear it all down again. Lines will lock to the grid visible in the background and make it easy to design neat structures, but moving the joining points doesn't seem to be possible and requires hard erasing to correct errors made. This can get frustrating on more elaborate designs and only proves to be really annoying once your line has stuck to the wrong grid point for the 10th time in a row.

In keeping with the paper theme, all the visuals including the interface are 'pencil drawn'. This works well for the game and is more utilitarian than elegant, but the designs don't feel as tacky as those used in other games using this style.

Paper Bridge is one of those great casual titles that's worth having around just to give your brain something to work on. Its simplicity may mean you'll move on after a while, but the uncomplicated bridge-building mechanics are appealing enough to keep you on track till the end.
