# Bubblarium vs Sand Block Crush

Both are free to download. Bubblarium sells 6 one-off in-app purchases and Sand Block Crush sells 7 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Bubblarium ships an update every 2 weeks, Sand Block Crush every 3 days. The most recent releases landed on November 5, 2026 and October 31, 2026 respectively.
