# Block Den vs Iron Saga

Both are free to download. Block Den sells 3 one-off in-app purchases and Iron Saga sells 8 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Block Den ships an update every 3 days, Iron Saga every 5 weeks. The most recent releases landed on October 25, 2026 and October 28, 2026 respectively.
