Each card is a syrup bottle with a colour word on its label, like RED, printed in an ink colour that may not match, like blue. The rule board above says either Tap the INK (the colour the word is printed in) or Tap the WORD (the colour the word names). Tap the matching colour among the four buttons; every button also has its own shape and its name, so the game works without telling colours apart. The syrup in the bottle drains as the timer: a wrong tap or running out of time costs one of your 3 lives. Right answers in a row build a streak multiplier, and golden bonus bottles, where word and ink match, score double. The rule flips more often as you go, the timer gets shorter, more colours join in and the buttons start swapping places. Sharpness for fun; challenge a friend to the same run.
