Watch the pen drawing in invisible ink. Can you guess what is drawn? Here's another release (the 5th in the Flash era), which called for party and champagne at that time. Anyway, it's not a tower-defense - it's barely even a game to be honest - but a puzzle with some educational elements. Whatever you consider, enjoy.
- Watch the pen moving and input the answer which best describes what's being drawn;
- 'Backspace' to erase one letter;
- There are many possible answers and some will give you more points than others;
- Score is also determined by how fast you finish a difficulty level and how many hints you use.
