Watch the colours light up, then repeat them back in the same order. One more is added every round — see how long you can hold the pattern.
The pads light up one at a time. Remember the order.
Tap the same pads in the same order once the lights stop.
Get it right and the sequence grows by one.
Every pad has its own note, so you can learn the tune as well as the colours.
Each pad carries a symbol, so colour is never the only clue.
Chilled to learn on, Fast when you want it to hurt.
