# Zero Below Zero vs Car Sort Puzzle

Both are free to download. Zero Below Zero sells 1 one-off in-app purchase and Car Sort Puzzle sells 7 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Zero Below Zero ships an update every 6 months, Car Sort Puzzle every 6 weeks. The most recent releases landed on October 15, 2026 and October 5, 2026 respectively.
