Our two children (6 & 8), and their cousins, love this game. When the penguin gets going, he throws out twelve tiles at a time, in a circle, and then someone calls out the category to find ('toes') illustrated on the tile, indicated by the coloured light on the penguin's head. He will change the category colour a few times, before repeating the tile-flinging. This repeats until all the tiles are used up, or the time runs out (indicated by a loud burp from the penguin). The winner is the one with the most tiles collected.
I'd advise playing the game on the floor - the penguin flips the tiles a surprisingly long way, and they're bound to fly off a smooth table. Plus, when the action gets rather frenetic, there's a distinct possibility of someone small lunging for a tile on the edge of the table, and missing... You are given more tiles than you need for a game, which is good for the variety, but also because cards have a tendency to disappear, being flung with unerring accuracy through tiny cracks under skirting boards etc, never to be seen again.
The penguins seems pretty solid. The tiles jam occasionally, and with the expected wear-and-tear on the tiles as they are grabbed by small hands, the problem will probably get worse as the game gets older & the tiles get more bent and dog-eared. However, a jam is usually solved by a gentle pull on the tile, and it doesn't seem to effect anyone's enjoyment.
