Free spelling and vocabulary games for kids, kindergarten to 8th grade

Find the words from your grade to solve the mystery.

Students are the detective. Each word from their grade powers the flashlight: read the hint, find the letters and the flashlight reveals the next clue of the mystery. After the last clue, they check their notebook and decide who did it. Friendly cases, from missing cookies to a comet in the night sky.

Make your detective and start a case

On a case your hero wears the detective outfit: a tan trench coat, a deerstalker hat and a magnifying glass.

Spelling game questions

Is the spelling game free?
Yes. The Missing Cookies is free from start to finish, all 11 clues, with no ads and no account. Members get every case, earn reward points and prizes, and keep each student's progress in their account.
What grades is it for?
Kindergarten to grade 8. Each grade has its own word list of about 120 to 180 words in English, Spanish and Portuguese, in three levels: Easy, Medium and Hard.
How are the words chosen?
Our lessons' vocabulary for the grade comes first, then the spelling patterns taught in that grade: short vowel words in kindergarten, blends and digraphs in grade 1, vowel teams in grade 2, prefixes and suffixes in grade 3, content words in grades 4 and 5 and academic vocabulary in grades 6 to 8.
Does it work on phones and tablets?
Yes. Letters go in with a big on-screen keyboard, and the notebook moves under the picture on small screens. On a computer, students can also type with the keyboard.
What happens after a wrong letter?
The flashlight dims and the battery loses one of its six segments. There is no fail screen: when the battery runs out, students put in new batteries and try the same word again.
