# DigDigDrill vs 連鎖玉

The clearest difference is in-app purchases: 連鎖玉 at none against DigDigDrill's 1. 連鎖玉 also leads on ads (none vs shown). DigDigDrill's advantage is update cadence (monthly vs every 5 months) and iOS requirement (12.0 vs 17.5). On price and device support there is nothing between them.

Both are free to download. DigDigDrill sells 1 one-off in-app purchase. 連鎖玉 asks for nothing beyond the download.

DigDigDrill ships an update monthly, 連鎖玉 every 5 months. The most recent releases landed on October 15, 2026 and October 9, 2026 respectively.
