Telescope Squares

Solve squares, roots, cubes and powers of two. Help pixel Galileo focus his rooftop telescope by solving squares, square roots, cubes and powers of two before the timer runs out, in this free math game.

Twist: Every question is a square, a square root, a cube or a power of two, getting harder each level.

Parody. Galileo Galilei has no involvement in making these games and does not endorse them. The character is an original pixel-art caricature.

How to play

  1. Tap or click the screen, or press Space, to start. Pick the answer with a tap or a click, or press 1, 2, 3 or 4.
  2. Level 1 asks for squares from 2² to 9². Level 2 asks for square roots of perfect squares up to 144.
  3. Level 3 brings squares up to 15² and powers of two. Level 4 adds cubes from 2 to 6 and squares up to 20², and level 5 mixes everything.
  4. You get a quarter more time per question than usual. A wrong answer or an empty timer bar ends the round.
  5. Press P or Esc to pause and M for sound. When the round ends, share your score and challenge a friend.

The story

Every lens in pixel Galileo Galilei's workshop has to be ground to exactly the right curve, and that means numbers, lots of them. Tonight the telescope on his rooftop observatory is blurry, and the only way to sharpen it is a round of Telescope Squares.

Each right answer turns the focus wheel a notch, and Jupiter slowly comes into view. A streak brings its little moons out one by one; a wrong answer smears the whole sky again. Get it sharp before the clouds roll in and the night is his.
