How to play
- Pick an unlocked floor of the Keep. Watch-Captain Orsa briefs you, then a short lesson shows the trick for that floor.
- Each floor trains one thinking skill: find hidden pairs from memory, tap the right picture, sort cards into groups, put snapshots in order, or answer before the timer runs out.
- Every answer comes with an explanation, right or wrong, so you learn the method, not just the score.
- Score 60% or higher to unlock the next level.
- Levels 1–2 are free with no account. A free account also unlocks levels 3–4.
- A small monthly subscription unlocks every remaining level.
Questions and answers
What age is Watchglass Keep for?
Ages 8 to 12, about grades 3 to 7. The first floor is a simple memory game; the last floors are truth-teller and liar puzzles that stretch 12-year-olds.
Which thinking skills does it train?
Working memory, focus and switching rules, turning and flipping shapes in your head, paper folding, seeing from someone else’s viewpoint, planning several moves ahead, and truth-teller and liar logic.
How is it different from Cipher Spire?
Cipher Spire is about finding rules: patterns, codes and clue chains. Watchglass Keep trains the skills those puzzles depend on: holding things in mind, ignoring distractions, turning shapes and planning ahead.
How does the memory game score?
A pair scores when you find it from memory. If you have already seen a card’s partner and then miss it, you still need to find that pair, but it won’t score. Careful play beats fast tapping.
