Why is thumbing allowed in the international Carrom game?

In international Carrom, "thumbing" (also the "thumb shot" or "back shot") is permitted as it gives more freedom to the players in shot-making. Compared to regular or informal Carrom rules, whereby players are restricted to hitting only with their index or middle finger to hit the striker in the forward direction, international Carrom rules (according to the rules set by the International Carrom Federation) do not restrict a player from striking from any of the sides of the striker and even using the thumb.

### **Rationale for Permitting Thumbing in International Carrom:**
1. **Enhances Shot Possibilities** – Permitting thumbing enables players to attempt more sophisticated shots, enhancing strategic play.
2. **Improves Accessibility** – Players with varying playing styles can deliver shots freely without limitations.
3. **Promotes Competitive Play** – Professional Carrom games call for precision and flexibility, and permitting thumbing offers more options for expert players.
4. **Uniform Rules** – The International Carrom Federation allows thumbing, providing consistency across the world's tournaments.

As professional Carrom focuses on skill and accuracy of shots over random limitations, thumbing is a valid and useful method in international competition.
