One puzzle, every day at 00:00 UTC
Riftboundle picks a new secret card from the Riftbound pool every day. The challenge is the same for every player in the world: identify it with as few guesses as possible, using only the attribute feedback each submission gives back.
- Green — exact match. Keep that attribute fixed on future guesses.
- Orange — a partial Domain match: some runes right, some wrong.
- Red with an arrow — numeric mismatch. The arrow says whether the secret card is higher or lower.
- Red without an arrow — try a different Type or Rarity.
- Open with a common, mid-cost Unit to probe several attributes at once.
- Lock Domain and Type before chasing numbers — that alone cuts the pool by 90%.
- Treat Energy, Power and Might as binary searches guided by the arrows.
- Don't repeat information. Every guess should test something you are still unsure about.
Your streak ticks up, your score is calculated from guesses and time, and — if you are signed in — your result goes to the leaderboard. The countdown shows when the next puzzle drops.
Signed out, your progress is still saved in your browser so you can come back later the same day. A free account syncs your streak across devices and makes you eligible for the ranking.
If some attributes are unfamiliar, read the attribute glossary — it explains Domain, Type, Rarity, Energy, Power and Might in plain language. You don't need a physical deck; a feel for how cards are shaped is enough.
