Three cups, one Roblu. The game shows you exactly where he’s hiding — then the cups start swapping places in pairs, faster and more often the higher the difficulty.

When the shuffling stops, tap the cup you believe in. The clock doesn’t start judging until the shuffle ends, so the watching is free — it’s your eyes during those swaps that win or lose this one.

How to play

  1. Watch the reveal — one cup tips up to show where Roblu starts.
  2. Track that cup through every pair-swap of the shuffle.
  3. When the cups stop, tap the one hiding Roblu. One guess.

Modes & difficulty

Easy shuffles four slow swaps; Medium speeds up through seven; Hard runs ten fast swaps back-to-back — four and a half seconds of continuous misdirection for a single tap of commitment.

One tip

Lock your eyes on the rim of the target cup and never look at the others — the shuffle can only lose you in the moment your gaze jumps. Saying the swaps quietly to yourself ("left… middle… left") keeps your attention glued through the fast finish.
