Yongjun was established in 2005 in Chenghai District, Shantou City, Guangdong Province, which is one of China’s largest manufacturing centres for toys and educational products.1 The company initially produced educational toys and mechanical puzzles before entering the growing speedcube market.

YJ first gained international attention between 2008 and 2010 through its Type D Cube (GuoYou), a budget-friendly speedcube that offered solid performance at a significantly lower price than competing models.2 During this period, it became one of the most popular entry-level cubes among hobbyists.

As speedcubing grew rapidly during the early 2010s, YJ expanded its product lineup to include virtually every World Cube Association (WCA) puzzle category. This expansion covered 2×2 through 7×7 cubes, Pyraminx, Megaminx, Skewb, Square-1, Clock, and numerous non-WCA puzzles.2

One of YJ’s most influential contributions to the speedcubing community was the creation of the MoYu brand around 2012–2013.2

MoYu was established as a premium sub-brand where independent puzzle designers could collaborate with YJ to manufacture innovative, high-performance speedcubes. Many early MoYu products were manufactured under the YJ umbrella, and older packaging often displayed both YJ and MoYu branding. Over time, MoYu developed into one of the world’s leading premium speedcube brands with its own distinct identity.

YJ focuses on offering affordable prices, reliable performance, beginner-friendly designs, durable construction, and continuous innovation.3 Rather than targeting only elite competitors, YJ emphasises products that provide excellent value for students, new cubers, schools, and hobbyists, whilst still offering competitive flagship models.

Over the years, YJ has released several well-known product families.

Budget series

These cubes are designed specifically for beginners and casual speedcubers. Models in this series include:

• GuanLong
• YuLong
• ChiLong
• SuLong
• RuiLong

These models became famous for offering smooth turning mechanics at extremely low prices.2

Big cube series

YJ is especially respected within the community for its larger cubes. Popular models include:

• YuSu 4×4
• YuChuang 5×5
• RuiShi 6×6
• YuFu 7×7

These puzzles helped make higher-order cubes significantly more affordable compared to earlier competitors.2

MGC series

The MGC line represents YJ’s flagship products. Introduced in 2018, MGC cubes feature factory-installed magnets, improved internal mechanisms, better stability, faster turning, and competitive-level performance.2

Many cubers consider the MGC line to be among the best value-for-money puzzles available. Popular models include:

• MGC 2×2
• MGC 3×3
• MGC 4×4
• MGC 5×5
• MGC 6×6
• MGC 7×7
• MGC Square-1
• MGC Megaminx
• MGC Pyraminx

In addition to speedcubes, YJ manufactures stacking cups, puzzle accessories, cube bags, timers, cube lubricants, magnetic building blocks, magic snakes, and educational toys.3 The company exports these products to dozens of countries worldwide.

According to the company, YJ operates multiple factories and production lines in Guangdong, China.3 These facilities include dedicated departments for product research, manufacturing, quality inspection, and exports. The company produces both OEM products and its own branded puzzles.

Within the speedcubing community, YJ is recognised for its excellent price-to-performance ratio, reliable beginner cubes, strong lineup of big cubes, and the popular magnetic MGC series.2 The brand is widely credited with helping expand affordable speedcubing worldwide.

Although brands such as MoYu and GAN often dominate the premium market segment, YJ remains one of the most respected manufacturers for budget and mid-range puzzles.

Some of YJ’s most influential releases include:

• Type D Cube
• GuanLong
• YuLong
• ChiLong
• YuSu 4×4
• YuChuang 5×5
• RuiShi 6×6
• YuHu Megaminx
• MGC 3×3
• MGC 4×4
• MGC 5×5
• MGC 6×6
• MGC 7×7
• MGC Square-1

These puzzles are frequently recommended to beginners and intermediate cubers due to their combination of affordability and performance.2

Yongjun has had a lasting impact on the speedcubing industry by helping drive down the cost of high-quality puzzles and accelerating innovation through brands like MoYu.2 Its products have introduced countless individuals to speedcubing, and its MGC series continues to be regarded as one of the strongest value-oriented lineups available. Through a balance of accessibility, engineering, and continuous product development, YJ remains one of the most influential manufacturers in modern cubing.
