# Stack The Tower vs Undead Siege

The clearest difference is rating: Undead Siege at 4.7 against Stack The Tower's 1.0. Undead Siege also leads on ratings volume (189 vs 1) and update cadence (fortnightly vs monthly). Stack The Tower's advantage is ads (none vs shown) and iOS requirement (7.0 vs 15.0). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Stack The Tower sells 1 one-off in-app purchase and Undead Siege sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Undead Siege holds the better App Store score, 4.7 against 1.0. That said, the two scores are not equally well evidenced: Undead Siege has 189 ratings behind it against 1, so its average is the more settled of the two.

Stack The Tower ships an update monthly, Undead Siege fortnightly. The most recent releases landed on November 1, 2026 and November 8, 2026 respectively.
