Topple has been on the Appstore since the time of my first iPhone 3G, so I took the liberty of calling this gifted puzzle game a legend. The principle of the game is certainly known to the vast majority, and for those who are not, the mentioned video will surely suffice.
The game is developed by the company Ngmoco, who also have, for example, the very successful online shooter Eliminate, the Rolando series and the sequel Topple. It is through the freely available unit that the developers are trying to entice you to buy the second sequel, which is improved with new levels, mods and actually everything that was criticized for the unit, especially the small number of levels.
Ngmoco, but they didn't forget about this possibly dusty first volume and added a new mode to it called Space mode! Of course, everything else is old, so download it before Ngmoco thinks twice :)
Good game, but I think it will always remain free, for users who want more, there is Topple 2 :).
That's true, even if Topple 2 is already Free, even if only with +Plus support, but it's still a surprising move from Ngmoco :)
