🧠 Track & Remember Challenge

Updating Span Test & Training
⚡ Quick Start
➤ How it works:
Numbers appear one by one on screen. A rule is shown (e.g., "EVEN numbers only") - you must remember only the numbers that match this rule.
➤ What to remember:
Depending on the Span Size (2-4), remember either the FIRST or LAST matching numbers. For example, with Span = 3, you remember 3 numbers that fit the rule.
➤ Example:
Rule = "EVEN numbers only", Span = 3
Full sequence: 3, 8, 5, 2, 9, 4, 7, 6
Position = Last 3 numbers
You are to remember: 2, 4, 6
➤ Position Modes:
LAST mode: Remember the last 3 EVEN numbers → Answer: [2, 4, 6]
FIRST mode: Remember the first 3 EVEN numbers → Answer: [8, 2, 4]
Random mode: Each sequence randomly uses FIRST or LAST
➤ Answer Modes:
Any Order: Click [4] [2] [6] in any order ✓
Sequential Order: Box 1 must be 2, Box 2 must be 4, Box 3 must be 6
