Timed Pattern and Logic Challenge

Four independent five-trial laboratory clocks

The timed pattern and logic challenge is divided into four experiments so one demanding question cannot consume the time reserved for the entire twenty-trial run. The countdown waits until the first answer or Logic Lens, stops after the fifth verified result, and resets before the next experiment begins. Easy allows 92 seconds per experiment, medium 80, and hard 68. The five-stop rail shows the current experiment's exact progress while Score, Streak, Time, Fuses, and Trial remain visible in the console.

Balance fuses, lenses, and streak scoring

Three glass fuses last across all four experiments. A wrong analyzer deducts 50 points, resets the streak, disables that choice for the current trial, and spends one fuse; spending the third shuts down the run. Easy includes four Logic Lenses, medium three, and hard two for the complete session. Each lens costs 40 points, reveals a useful reasoning step, and highlights the supported answer without selecting it. Correct results award a 220-point base, remaining seconds, and a growing streak bonus. Clearing an experiment adds another time-sensitive reward, while completion adds bonuses for unused fuses and lenses.

Pause and restart keep state predictable

P, Escape, or the Pause control freezes an active clock without changing the prompt, analyzer order, rejected choices, score, streak, fuses, lenses, or remaining time. Resume continues from the same second. R or Restart creates a fresh order at the selected level, and choosing Easy, Medium, or Hard starts a clean run with its matching record pool, clock, and lens allowance. All timers, scoring, randomization, explanations, and transitions run locally in the page rather than through a server session.
