Fill the blank in each foreign sentence, every answer leaks its letters into the next, so the gaps interlock.
You face a ladder of fill-in-the-blank sentences. Each consecutive pair shares a vocabulary word, so when you solve one blank its letters leak into later blanks, the independent sentences interlock like a crossword. Work down the chain, using letters you've already revealed to crack the harder gaps.
Gapstorm weaves fill-in-the-blank vocabulary into an interlocking deduction puzzle, learning words in context.
Fill-in-the-blank sentences are the cloze test, a standard measure of reading comprehension and language proficiency.
Having each solved blank leak letters into later ones is the original chaining.
That chain changes what the test measures. A standard cloze scores each gap independently; linking them means an early answer constrains later ones, so the exercise rewards consistency across a passage rather than word-by-word guessing.
