The challenge mode is definitely beatable (have beaten it myself some times already ;) ). Where a tile spawns depends on where you are standing during the spawn (only the tile and not x/y coordinates). But I watched our team mate play it through and he almost always got the same moving tiles. If you are moved out or locked in, try to stand on another tile, while it shifts. So you can kind of predict a pattern, the thing is that the pattern changes depending on where you walk through.
