# Block Invaders vs YUSEONG

The clearest difference is ads: Block Invaders at none against YUSEONG's shown. YUSEONG's advantage is update cadence (every 2 months vs every 12 months) and iOS requirement (13.0 vs 16.0). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. Block Invaders sells 2 one-off in-app purchases and YUSEONG sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Block Invaders ships an update every 12 months, YUSEONG every 2 months. The most recent releases landed on November 13, 2026 and November 2, 2026 respectively.
