Fun brain teasers worksheet featuring word puzzles and riddles for mental exercise.

- HISTORY HISTORY HISTORY: "History repeats itself"
- MEREPEAT: "Mirror, mirror on the wall" (or "Repeat")
- read: "Read between the lines"
- Chimadena: "Chimadena" is a play on "Chimney" and "adena," but it's likely meant to be "Chimney" or "Chimadena" as a visual pun for "Chimney" (though not a common phrase). Alternatively, it might be "Chimadena" as a misspelling of "Chimenea," but that doesn't form a common phrase. Given context, it might be intended as "Chimney" with a twist, but no standard phrase fits perfectly.
- millio1n: "Million"
- 1 knows: "No one knows"
- time time: "Time after time"
- BIRD: "Bird in the hand"
- VA DERS: "Vaders" (as in Darth Vader) or "Invaders," but likely "Vaders" as a play on "Darth Vader." However, no common phrase fits directly. It might be "Vaders" as in "Darth Vader," but that's not a phrase. Alternatively, it could be "Invaders," but again, not a common brain teaser phrase. Perhaps it's "Vaders" as a misspelling of "Vaders," but no standard phrase fits.
- RIGHT RIGHT: "Right on right"
- FLUBADENCE: "Flubadence" is not a standard word. It might be a play on "Flu" and "Abundance," but no common phrase fits.
- etad: "Date" (spelled backwards)

Given the nature of brain teasers, some answers may be more straightforward than others. Here are the most likely intended answers:

- HISTORY HISTORY HISTORY: "History repeats itself"
- MEREPEAT: "Mirror, mirror on the wall"

- VA DERS: "Vaders" (as in Darth Vader, but not a phrase) or "Invaders"
- RIGHT RIGHT: "Right on right"
