Realistic Test Mode

This is the Realistic Test Mode of the Pincode Game, designed to replicate the actual Optiver Zap-N assessment experience. You'll face three distinct rounds, each lasting one minute:

Round 1 - Repeat

In the first round (questions 1-10), you'll need to memorize and input sequences exactly as they appear. For example, if you see "12345", you should input "12345". This tests your basic sequence memory.

Round 2 - Reversed order

For the second round (questions 11-20), you'll need to input the sequences in reverse order. For example, if you see "12345", you should input "54321". This tests your ability to manipulate sequences mentally.

Round 3 - Sorted order

In the final round (questions 21-30), you must sort the digits from lowest to highest before inputting them. For example, if you see "31524", you should input "12345". This tests your ability to reorder sequences.

Important Notes

• Each round is timed separately (1 minute per round)
• The difficulty increases with each correct answer
• You'll receive a confirmation message before starting rounds 2 and 3
• Your final score combines performance across all three rounds

Rules

• Each sequence will be shown one digit at a time
• The number of digits will increase after correct answers and decrease after incorrect ones
• The range is 4 to 8 digits per sequence
• You gain 1 point for correct answers and lose 1 point for incorrect ones
