iPhone App Solves Rubik’s Cube In 20 Moves Or Better


Now you can use this century’s greatest gadget to do battle with last century’s most-beloved geek toy.

A new iPhone app called CubeCheater helps you solve the classic Rubik’s Cube puzzle toy using a mix of sophisticated algorithms and simple image-recognition technology. CubeCheater sells for $1 in the App Store.

Here’s how it works. You take six pictures of your mixed up Rubik’s Cube using the iPhone’s camera — one photo per side. If you have an iPod Touch, you can also tap in the color combos manually. CubeCheater is able to recognize the placement of each colored square and generate a map of your cube. It then figures out the quickest path to solving the puzzle and gives you a set of easy-to-follow, step-by-step instructions.

Using software to solve Rubik’s Cube isn’t new. Mathematicians have been bending their brains into virtual cubes since the toy’s debut in the late 1970s, but the math behind the puzzle-solving continues to evolve.

The current guru of Rubik’s computer algorithms is Herbet Kociemba, creator of the open source Cube Explorer software program. Kociemba’s solver software is currently used by computer science students at universities to build cube-solving robots, some of which also use a camera and image-recognition tech to figure out the color patterns.

CubeCheater uses Kociemba’s algorithm to solve scrambled cubes. The app can also be tweaked to solve cubes with nonstandard color variations. CubeCheater even works in reverse; create a virtual mixed up cube inside the app, and it will tell you how to twist a solved cube to match your creation. Could be useful in making pretty geometric patterns.

Drought has plunged water levels to the lowest in China in decades. The temperatures have also soared to record levels, and hydropower plants failed to meet the sharp rise in power demand. However, this is just a glimpse of the worst things to come. Floods, droughts, and record-breaking temperatures would have a catastrophic effect on […]

India says disengagement along disputed area with China to be completed by September 12

India’s foreign ministry said on Friday that disengagement along a disputed border area with China will be completed by Sept. 12.

How to make EVs without China’s supply chain

Two electrifying moves in recent weeks have the potential to ignite electric vehicle demand in the United States. First, Congress passed the Inflation Reduction Act, expanding federal tax rebates for EV purchases. Then California approved rules to ban the sale of new gasoline-powered cars by 2035. The Inflation Reduction Act extends the Obama-era EV tax […]

Anti-India forces: Techniques and agendas exposed

In the post-cold war era, India has moved from a policy of non-alignment to a policy of multi-alignment. This means that India has friendly relations with almost all-powerful and developing nations. Today India is carving out a unique path for itself. Such an approach provides prominence and exposes India to the harmful behind-curtain activities by […]

Taiwan’s Kinmen serves as a reminder of China’s aggression

Taiwan’s frontline island of Kinmen was once again in the headlines when President Tsai Ing-wen paid tribute this week to the soldiers and civilians who “operated in solidarity and safeguarded Taiwan” 64 years ago. On Aug. 23, 1958 mainland Chinese troops attacked Kinmen in a key battle that marked the beginning of the Second Taiwan […]

Terrorism: The glue that holds China and Pakistan together 

The father of communism, Karl Marx, once famously said — “We have no compassion, and we ask no compassion from you. When our turn comes, we shall not make excuses for the terror”. This statement summarises how terrorism and communism go hand in hand. Maoist China alone destroyed between 44.5 to 72 million lives. During […]

‘New normal’ across the Taiwan Strait as China threat looms ever closer

China is attempting to establish a “new normal” across the Taiwan Strait, eroding self-ruled Taiwan’s territorial control and increasing the threat of a strike with each military sortie, officials and analysts say. Beijing has ramped up military maneuvers in the 110-mile (180-kilometer) wide stretch of water that separates Taiwan from mainland China — and the […]

When Beijing was burning, Xi was playing personal games 

A great fire destroyed Rome for six days in the summer of AD 64. Famous Roman historian of that time, Tacitus, recorded that 70 percent of the city was destroyed and half of the city’s residents were displaced. Roman ruler Nero was accused of being indifferent, ineffective, and careless. The end result of this neglect […]
