Drag the colored boxes into the hidden correct order.
Fill all the slots — the game checks automatically.
Correct positions lock in.
Wrong ones snap back.
Use your attempt history to crack the code. 60 seconds.
Crack the hidden colour sequence before the 60-second timer runs out. Drag colours into slots and submit — correct positions lock in for points.
Each sequence has a fixed correct order. When you submit: correct positions earn +10 pts and lock permanently. Wrong positions lose −5 pts and snap back to the palette. Use your attempt history to narrow down what goes where.
Every 2 sequences you crack, an extra colour is added to the palette — making each new puzzle harder than the last.
Each attempt gives you partial information. Interpreting feedback and updating your mental model is pure logical reasoning under time pressure.
Tracking multiple attempt histories while testing new hypotheses exercises your working memory — the same system used in maths and reading comprehension.
