# IEEE Volta vs Lights Out

The clearest difference is in-app purchases: IEEE Volta at none against Lights Out's 1. IEEE Volta also leads on ads (none vs shown) and iOS requirement (8.0 vs 15.0). Lights Out's advantage is update cadence (weekly vs fortnightly). On price and device support there is nothing between them.

Both are free to download. Lights Out sells 1 one-off in-app purchase. IEEE Volta asks for nothing beyond the download.

IEEE Volta ships an update fortnightly, Lights Out weekly. The most recent releases landed on November 2, 2026 and November 9, 2026 respectively.
