Tochki

Tochki is a connect-the-dots game for children who are learning numbers. Tap the dots in order and a line follows your finger from number to number; close the shape and it fills with colour and becomes a cat, a fish, a fir tree or a rocket. Six stages add one idea at a time: count to 5, to 10, to 20, count by twos, count down from 10 for a rocket launch, and count by tens up to 100. Each dot shows its number in words, in English or Bulgarian. A wrong dot wobbles and costs a star, never the game, and after two misses the right dot glows. Eighteen pictures, all drawn by code. It plays in the browser with a mouse, touch or keyboard.
