# Can Knockout vs Stack Block Blast

The clearest difference is in-app purchases: Stack Block Blast at none against Can Knockout's 10. Stack Block Blast also leads on ads (none vs shown) and update cadence (every 7 months vs every 36 months). Can Knockout's advantage is ratings volume (5 vs 1). On price, review sentiment and device support there is nothing between them.

Both are free to download. Can Knockout sells 10 one-off in-app purchases. Stack Block Blast asks for nothing beyond the download.

Stack Block Blast holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Can Knockout has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Can Knockout ships an update every 36 months, Stack Block Blast every 7 months. The most recent releases landed on November 2, 2026 and November 4, 2026 respectively.
