# Rubik's Cube Hobby Group

The Rubik's Cube hobby group, SnT Council at IIT Kanpur is a group for cubing enthusiasts. They conduct workshops throughout the year for 3x3x3(the original Rubik's puzzle) as well as higher puzzles. Facebook page

*"There is Solving , then there is Speed-Solving."*

The group has a wide variety of puzzles which can be issued on request by contacting the Group Leaders.

Students can also pursue projects under this Hobby Group during summers.

## History

The Rubik's Cube Hobby Group was started in 2008 and was the first such group in the country.

The group organised the first official World Cube Association competition in India.

An Asian Record was set in this competition by Bernett Orlando in the square-1 event.

## Workshops

The Hobby Group organizes workshops throughout each semester for teaching various methods of solving the Rubik's Cube and various other higher puzzles

### Odd Semester

- 3x3 (Beginner method)
- 2x2 (Beginner method)
- 3x3 (Intermediate method)
- 3x3 (F2L method)

### Even Semester

- 4x4
- 5x5
- Pyraminx
- Megaminx
- Blindfold Solving (Oh yes!)

## Competitions

### Takneek

Takneek is the annual Inter-Hall science and technology competition consisting of several events from each club and hobby group under SnT Council.

Events held as part of Takneek :

- 3x3x3 (Freshers)
- 3x3x3 (Seniors)
- Team Blindfold (Team-BLD)
- Medley Relay

The Team Blindfold event has teams of two students - one fresher and one senior, one of whom is blindfolded with the 3x3x3 Rubik's Cube and the other must give instructions for solving it without touching it himself.

## Indian Open Rubik's Cube, Techkriti

IORC(Indian Open Rubik's Cube) is an official WCA (World Cubing Association) event conducted during Techkriti. This event attracts speed cubers from other institutions all over India who, along with the participants from our campus, compete for cash prizes and goodies.

Events conducted:

- 2x2x2
- 3x3x3
- 3x3x3 (One-handed)
- 4x4x4
- 5x5x5
- Pyraminx
- Megaminx
- Blindfold(BLD)
- Multi-BLD
- Fewest Moves Challenge (FMC)
- Square-1 (2015 onwards)

Any record set during an official WCA competition is displayed on the person's profile on the WCA website. In IORC 2015, a new National Record was set by Bhargav Narasimhan for best single solve time (51.65 seconds) and average time (1:03.07s) for solving the Megaminx.

## Projects

Some of the projects pursued by students in Summer:

### Mathematical Analysis and Programming

This project aims at studying the mathematical aspects of a Rubik's cube,mainly it's analysis using *Group Theory*.

Mathematical analysis of Rubik's Cube becomes important in *Fewest Move Challenge*.

Project wiki

Students doing this project also implemented an optimal solver for the 2x2x2 cube,which on average takes only 2-3 moves more than fewest move solution.

### Blindfolded Solving

As the name implies, this involves learning how to solve the puzzle blindfolded.

### Fewest Moves Solving

This is an event where competitors attempt to solve a puzzle (almost always the 3x3x3) in as few moves as possible, starting from a given scramble. The usual turn metric is HTM.
