I can't think of anything that is more bite-sized gameplay than this. The video really does show you pretty much everything. Games are super short and tricky (you'll be impressed with yourself the first time you manage to stack 10 totems) but incredibly fair. When you mess up it'll be because you screwed up, not because the game made it hard. Most totems fall on a slight curve, but some (indicated with their fall path) come straight down. There's also the occasional totem that straightens the tower.
You aren't going to be hooked by this game for your first few rounds, but hold out until you unlock your first totem. By that point the game will have dug it's "one more round" hooks into you. ...but don't expect skill to come too quickly. As I write this the global high score is only 52!
