Ripple

Ripple treats history as a row of dominoes. A day's puzzle opens with one real event, and your job is to predict the next one in the chain. You pick from four options, the game reveals the answer with a short explanation of how one thing caused the other, and that answer becomes the starting point for the next question. Three predictions make a full chain.

The chains lean towards surprising links rather than famous dates: how a printing mistake on a map ended up naming two continents. Because every answer comes with its reason, a wrong pick still teaches you something, and the game marks it as a wrong prediction with the explanation rather than just a red cross.

Once per game you can use a hint that removes two wrong options, at the cost of half the points for that question. Results can be shared, a streak counts consecutive days, and past chains can be replayed from an archive without touching your streak. Signing in is optional and adds you to a leaderboard that weighs average points, games played and streak. It suits players who like history for its stories of cause and effect more than for memorised years.
