It's a Wolfoo birthday party - and every picture is waiting for its colors! Tap a color from the palette, then tap the squares that match it. Pinch or scroll to zoom right in on the tiny details, and drag to move around the canvas. When the last square is filled the picture comes alive: the pixels melt into the finished artwork and the confetti flies. 30 hand-made birthday pictures to uncover - cakes, candles, balloons, presents and party friends - each with its own music, and your progress is kept so you can come back to the next one any time. Calm, tidy and no timers: colour at your own pace
