Brain Test 5 Level 23
๐ Walkthrough
Overview
You face an alien in a rock-paper-scissors contest. As the rounds go on, the alien grows extra heads and hands that reveal the gesture it is about to throw, and you must pick the counter that beats it each time until you win the match. The counters follow the standard rules: rock beats scissors, scissors beats paper, and paper beats rock.
- Difficulty: Hard
- Estimated moves: 3
Step-by-Step Solution
- Watch the alien's hands before you choose. The extra heads and hands it grows display the gesture it plans to throw, so read that visible shape instead of guessing randomly.
- Identify its gesture as rock, paper, or scissors. Rock is a closed fist, paper is a flat open hand, and scissors are two extended fingers.
- Choose the counter that beats it: play rock against scissors, scissors against paper, and paper against rock.
- Repeat the read-and-counter loop for each round. The alien changes its gesture between rounds, so re-examine its hands every time rather than replaying your last winning choice.
- Once you win the required rounds against the alien, the checkmark appears and the match ends.
- When reading the alien's hand, compare it against the three shapes one at a time: a closed fist is rock, a flat open palm is paper, two fingers is scissors, so you do not mislabel a half-open hand.
- If a round loses, re-check the counter rule against the gesture it threw; keep the cycle straight so rock answers scissors, scissors answer paper, and paper answers rock for the next win.
- Between rounds, clear your memory of the previous gesture; the alien grows a fresh hand for each throw, and replaying your last winning counter against a new gesture will lose the round.
Strategy & Reasoning
The level turns a chance game into a reading task. Normally rock-paper-scissors is unpredictable, but here the alien exposes its move through the extra heads and hands, which removes the guessing. The whole challenge is recognizing the three hand shapes and remembering the cycle that beats them. Keeping the counter rule in one sentence helps: rock crushes scissors, scissors cut paper, and paper covers rock.
The trap is overcommitting to one winning throw. After you beat a gesture once, it does not mean the same counter works again; the alien grows new heads and hands for each round, showing a different planned move. There is also no reason to read the faces or extra heads for a clue, because the gesture is carried by the hands themselves. If your choice loses, the visible hands give the counter rule you should have applied, and you can re-check the three shapes before the next throw.
Tips & Common Mistakes
- Read the alien's hands, not its heads or expression; the planned gesture is shown by the hand shape.
- Match the counter correctly: rock beats scissors, scissors beats paper, paper beats rock.
- Do not reuse your previous winning throw; each round displays a fresh gesture that needs its own counter.
