I come in many shapes and sizes, and can be solved by kids and adults alike. I am most commonly made of cardboard or wood, but exist in the virtual wolrd too. The harder you struggle to complete me, the sweeter the reward when I'm finally finished.

I wear a rough brown coat, contain water that’s sweet and float, grow high on a palm in the sun, and people use my milk and flesh when the work is done. What am I?

I'm a glowing rectangular pocket-dwelling beast, That feeds on your thumbs for a daily feast. You stare at my face till your eyeballs blur, Then panic and scream when I start to purr!

On it. Hit it. Too many curves And you’ll want to quit it.

Worn by the rich elite, half a pair of glasses, singular lens symbol of wealth.
