I.T. Kid

Skim the bay to fill the tank, then drop the water on a burning forest from the air.

Hop a frog across a busy road and a log-strewn river to the home bays.

Hold an island against a round of incoming attack.

Hold the map against a stream of enemies for as long as you can in this 2009 defence game.

Escape a hard-edged cube room by room, dodging the spikes and rotaries that guard every exit.

Guide the digger through the tunnels, collect the gold and clear each level before the clock runs out.

Twelve icicles and one cliff -- plant them as a staircase for a penguin who can only manage 1.2 metres a hop.

The yeti has a llama and a mouthful of ammunition -- spit at the penguins before the clock runs out.

A yeti swings up a tree by his fingertips -- click at the top of each arc to reach the next branch.

Headfirst into a mosh pit of penguins -- ten clicks to keep the yeti off the floor and send him as far across the room as the crowd can throw him.

Race ten penguins down a long slope and score the tricks more than the win -- every jump is points, and the penguins you bump get angry.

Surf the big one: stay on the crest, throw a turn for style and scoop penguins out of the water before the wave finally closes over you.
