I thought I’d write up a quick post in response to some of the reviews left for Toobz and Toobz-Free…
First of all, it may not be obvious, but it’s OK to let water run out the sides of the screen. Just like the loading screen shows — you don’t always need to have your water end up in a “stopper.” In fact… a quick tip is anytime you get a cross (+) that doesn’t fit very well, throw it into one of the four corner spots.
Second — there’s no rotating of the toobz… we initially had rotation, but it almost made things too easy.
Third — you can replace toobz pieces you’ve already placed, except in the ‘Hard’ game setting. So… if you keep getting the same piece over and over and it just doesn’t fit into your plan, just keep tapping the same square and replace it.
Finally… we promise that the choice of the next Toobz piece is completely random! 
It might not seem like it sometimes, but believe us… it’s as random as computers can get.
Thanks for reading, and good luck!
