Most trivia games test static knowledge—"What year did X happen?"
Ripple is different. It tests causal reasoning.
You're shown a real historical event and asked to predict what happened next. Get it right, and you follow the chain deeper—3 events total, each consequence leading to the next.
Ripple #728 🌊
Event 1: ✅
Event 2: ❌
Event 3: ✅
Chain Score: 2/3
It's not about memorizing dates. It's about understanding how decisions ripple through history—how consumers react, how companies pivot, how one invention enables another.
New puzzle every day. Same puzzle for everyone.
