Cognitive Assessment · Optiver-style
Zap-N
Nine cognitive games. Reaction time, risk management, planning, selective attention, working memory, task-switching, mental arithmetic, pattern recognition, and logical deduction. Modeled on the Optiver Zap-N trader-candidate assessment.
Games
What you'll face
- 1 · Stock Master Reaction time. A bar rises at varying speeds — click when it enters the green zone. Tests split-second patience: not too early, not too late.
- 2 · Balloon Risk management. Pump a balloon to earn coins, but each pump raises burst probability. Cash out to bank earnings, or push for more. Based on the Balloon Analog Risk Task (BART).
- 3 · Skyscraper Planning. Rearrange colored blocks across three stacks to match a target layout using as few moves as possible. Tests multi-step look-ahead under constraints.
- 4 · Shapeshift Selective attention. A circle or square flashes left or right. Respond to the shape, ignoring position. Based on the Simon effect (1963).
- 5 · Digit Working memory. Digits flash one at a time — recall them in order, then in reverse. Sequences scale up until you fail twice at the same length.
- 6 · The Switch Cognitive flexibility. Left panel = addition problem. Right panel = arrow comparison. Screen position tells you which task to solve. The challenge is the constant switching.
- 7 · Number Box Mental arithmetic. Use all four given numbers with any arithmetic operations to reach a target. A modernized 24 Game — creativity under pressure.
- 8 · Code Compare Pattern recognition. A numeric code appears at the top. Match it to one of four options before the timer runs out. Speed tightens each round.
- 9 · Figure It Out Logical deduction. A hidden figure has three attributes (shape, color, pattern). Guess and receive correct/wrong feedback per attribute. Fewer guesses = higher score. Mastermind-style.
