X-Blind Coding Arena is a fast-paced technical event where teams of two solve programming challenges without directly viewing the screen. The event focuses on logical thinking, communication, memory, debugging skills, and teamwork. Designed to be beginner-friendly at the start and progressively challenging, it keeps both first-year and senior students actively engaged.

1. Team of 2 (Thinker & Coder) Ensures teamwork and communication skills.
2. Only Thinker speaks, only Coder types Avoids confusion and maintains discipline.
3. Screen remains covered during coding Maintains the core concept of blind coding.
4. No internet, mobiles, or external help Ensures fair competition.
5. Allowed languages: C, C++. Commonly known languages for all years.
6. Round-wise progression:

Round 1: Read & Write -> Engaging and beginner-friendly
Round 2: Debug Battle -> Tests debugging and logic
Round 3: Chit Logic -> Pure logic & communication
Round 4: Sudden Death (if required) -> Final decision in case of tie

7. Time limits strictly followed Tests performance under pressure.
8. Misconduct or disturbance leads to penalty/disqualification Ensures smooth event execution.
9. Judges’ decision will be final Avoids disputes.

Read & Write Challenge:

• One participant is designated as Thinker, the other as Coder
• The Thinker can view the code/problem (via projector or revealed screen)
• The Coder writes the code while the system screen remains covered
• The Thinker verbally guides the Coder
• The Coder is not allowed to speak or uncover the screen

Debug Battle:

• A buggy or incorrect code is displayed on the projector for a limited time
• The Thinker observes and identifies errors (logical/syntax)
• The screen is then covered
• The Thinker explains corrections verbally, and the Coder rewrites the corrected code

Chit Logic Challenge (Final Round):

• The Thinker randomly picks a chit containing a logical problem statement (Example: “Find second largest element without sorting”)
• No code or hints are displayed on the screen
• The Thinker explains the logic verbally in steps
• The Coder converts the logic into executable code without screen visibility.

Sudden Death (Tie-Breaker):

(This round will be conducted only if the final teams cannot be decided after Round 3.)
• Only tied teams will participate
• One problem will be given
• Thinker gets 20 seconds to read the problem
• Screen remains covered during coding
• Thinker explains logic verbally, Coder writes the code
• First team to produce correct output wins
• If still tied: least time & minimum syntax errors considered.
