So some idiot tweeted about Zen Bound 2 being dirt cheap and a cool relaxing puzzle game. Challenge accepted.
Zen Bound has, like most good puzzle games, a real simple mechanism which becomes pretty complex. You need to "paint" a figure with a piece of tight string. Figures can be as simple as a straight-forward geometric shape or as complex as hyper-intelligent pan-dimensional beings (which for some strange reason always look like monkeys).
You operate the puzzle by turning the object around its centre and depending on how gordian your contraption looks, you get more or less points (fittingly named karma).
So where is the Zen in this? Well, getting frustrated with it is hard. In the majority of cases you can see if your next step is going to succeed or not. The only "doh'grrrr"s I encounter are when you think you are clever and wind up running 2cm string short or forgot that one round of string is blocking your next super-smart move. The music helps as well. It has a hint of old-fashioned múm and other nice ambient tunes, which I like.
But, in true Top Gear fashion, we need something to put our axe in after being so positive the entire review: playing it for a longer period on the iPad is not so Zenny for your neck, shoulders and arms unless you have artificial helpers (or gravity).
But overall, it is worth more than a bag or rice and at the moment, it is cheaper than that. Available on Steam and the Apple stores, so you could also just use your mouse :P
