Tap to blow out the candles; tap again to light them. Hands-on: pull a candle out, push it in.

A birthday cake is a sweet, frosted cake with candles on top, often one for each year. People sing to the birthday person, who makes a wish and tries to blow out all the candles in one breath.

This cake starts with its candles lit. Tap to blow them out, with a puff of smoke from each wick, and tap again to light them. In the Splash tab, choose from one to nine candles, the colors of the frosting and the drip, and a vanilla, chocolate, red velvet or strawberry sponge. A candle flame needs air: blowing hard pushes the hot, burning gas away from the wick, and the flame goes out. With ✋ Hands-on on, pull a candle out of the cake (it goes out) and push it back into its hole, where it clicks home alight again; a candle set down on top lies on the frosting.
