# Space Merge X vs Tumble Balls

The clearest difference is ads: Space Merge X at none against Tumble Balls's shown. Tumble Balls's advantage is update cadence (every 3 days vs every 3 months) and iOS requirement (10.0 vs 13.0). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Space Merge X sells 1 one-off in-app purchase and Tumble Balls sells 7 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Space Merge X ships an update every 3 months, Tumble Balls every 3 days. Both last shipped on November 3, 2026.
