# Brainblast vs World History Slots

The clearest difference is ads: World History Slots at none against Brainblast's shown. Brainblast's advantage is ratings volume (590 vs 4) and update cadence (every 2 days vs every 5 days). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Brainblast sells 10 in-app purchases, starting at $149.00 per month and World History Slots sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.6 for Brainblast against 4.5 for World History Slots. That said, the two scores are not equally well evidenced: Brainblast has 590 ratings behind it against 4, so its average is the more settled of the two.

Brainblast ships an update every 2 days, World History Slots every 5 days. The most recent releases landed on November 8, 2026 and November 5, 2026 respectively.
