Begin the battle by arming each player with a Denko Catcher, which is a retractable yo-yo that has a single magnet securely embedded in its covered base. An adjustable loop at the end of the cord attaches the Denko Catcher to the player's finger, enabling the catcher to quickly return after being thrown toward the ground to retrieve Denko Disks. If the magnetized tip of the catcher lands on the metal-coated center of a Denko Disk, the disk will adhere to the catcher. The player who threw the catcher keeps the disk.
Denko Catchers and Denko Disks come in different weights, colors, and themes. Depending on their rarity, size, and shape, Denko Disks are valued anywhere from 10 to 50 points each. Highly collectible 100-point disks will be in limited circulation. At the end of each round, players add up the points displayed on their disks to determine who is the Denko Master.
Kids can get started playing Denkosekka with the Denko Starter Pack. This retails for about $9.99 and includes a catcher, four disks, and an advanced warrior guide. The Denko Battlemat Pack includes four battlemats, an exclusive disk, and a collector's poster. This pack also retails for about $9.99. Collect more Denko Disks with the Denko Disk Pack ($2.99), which comes with three disks of varying value and rareness. Battle it out with the Denko Battle Set's two catchers, eight disks, two battlemats, and collector's poster. This retails for about $19.99.
This game is great because it takes the fun of yo-yos and adds high-stake battle drama. Boys can compete head-to-head or in teams, or even play on their own to enhance their Denkosekka skills. That said, there is a level of skill and a learning curve involved. Kids who are willing to practice can become very adept at this game. Other kids may find it frustrating. This has been a hot, competitive game in Japan and is now making its U.S. debut.
