Sort Yard

A conveyor of numbered crates needs ordering. Pick a sorting strategy and run it; the crates compare and swap on the belt while you are charged for every comparison and every swap. The cheapest strategy for this exact row is par, beat it to clear the yard.

• Choose from bubble, insertion, selection and quicksort
• You pay one cost unit per comparison and per swap
• Same crates, very different bills, that gap is algorithmic complexity

• Desktop: click a strategy button, then Run sort; Reset replays, New crates makes a fresh row in practice
• Phone & tablet: tap the strategy and the Run button

• Daily: a shared crate arrangement seeded from today's date
• Practice: generate new arrangements freely

• Insertion is cheap when the row is already nearly sorted; quicksort tends to win on big random rows
• Read the arrangement label and match the strategy to it to hit par

Sort Yard makes sorting-algorithm cost visible by letting you run different strategies on the same data.

• Skills: sorting algorithms, algorithm efficiency, comparing strategies, computational thinking
• Best for: roughly grades 8–12 (ages 13+)
• For parents & teachers: see why some sorts beat others.
