Type the word and Hopper the frog jumps across a giant keyboard, one key at a time! Learn where every key lives, starting with the home row. Use a real keyboard, or tap the keys on the screen. With 3D glasses the keyboard stretches away from you.

Do you have 3D glasses? Red-green, red-blue and red-cyan glasses all work.

3D GLASSES

Check the 3D
How deep?
Less depth is easier on the eyes. More depth pops out more.
1. Hide the green bar
Put the glasses on and cover the eye behind the green lens, so you look only through the red lens. Slide left until the green bar disappears.
2. Hide the red bar
Now cover the eye behind the red lens, so you look only through the green lens. Slide left until the red bar disappears.
3D mode is just a fun way to play. If your eyes feel tired, take a break or play without glasses.
HOW TO PLAY
A word appears at the top. Type its letters in order. The next letter is yellow, and that key glows on the 3D keyboard.
Each right key makes the frog hop onto it. A wrong key flashes and counts as a slip.
The bottom-row lesson also uses the vowels and L, so the words make sense.
Home row: rest your left fingers on A S D F and your right fingers on J K L ;. The bumps on F and J help you find them without looking! The hint line says which finger to use.
On a phone or tablet, tap the keys on the 3D keyboard instead.
Few slips earns ⭐⭐⭐ (97% right or better), 90% earns ⭐⭐. Stars open new lessons and new hoppers.
HOW 3D WORKS
Try this: hold up a finger and look at it with one eye, then the other. It jumps! Your brain uses the jump between your eyes to see depth: stereo vision.
The game draws the keyboard twice, from two eyes a little apart, in red and in green (or blue). The glasses give each eye its own picture, so the bottom row is close to you and the top row is further away, just like a real keyboard on a desk.
Keyboard fact: the letters are not in ABC order! This QWERTY layout (look at the top row) is about 150 years old, from typewriters. People who type without looking use the home row as their base and reach up and down from it.
