Kamon in MyRin sorts Japanese family crests onto lacquer stands. How to read the crests, the rules, hard mode in gold, and the history of kamon.
Japanese family crests were designed to be recognised instantly: on a banner, a kimono, a roof tile. Kamon, the MyRin crest puzzle, asks your eyes for the same skill. On easy, colour does most of the work. On hard, every crest is rendered in the same gold and most of them are hidden, so you sort by outline and memory alone. Here is how to read the crests, and where they come from.
Tap a lacquer stand to lift its top crest, then tap another stand to place it. A crest only lands on an empty stand or on an identical crest. You win when every crest of a kind is gathered on one stand. Easy and medium give each crest its own colour; hard stacks the stands seven deep, uses all eight crests, drops the colour and conceals everything you have not uncovered.
The mechanics are shared with Hue and Temari, so the same buffer rule applies: protect your empty stand, and never spend it on a crest you cannot immediately build on.
On hard, there is no colour to skim, so you need to recognise each crest from its outline in a fraction of a second. Four of the crests carry most of the load:
In play, the pointed crests read fastest: a star and a triangle stand out against round petals even in a quick glance. That makes kikyo and uroko the best anchors. Find those first, then read the rounded crests against them.
The Kamon game page lists the rules for each difficulty and the crest-reading tips.
Open the Kamon game pageAccording to Nippon.com, kamon are thought to have come into use around the tenth century among the Japanese aristocracy, as status markers in the Heian period. In the Muromachi period some commoners began using crests, and in the Edo period common people were allowed to choose their own, with two exceptions: the chrysanthemum crest of the imperial family and the hollyhock crest of the Tokugawa.
Between those two stages, warrior families put crests on banners and equipment, where a crest had to tell allies from enemies at a distance. That battlefield use is where the kamon design style was tested hardest.
Today an estimated 20,000 to 25,000 family crests are in use in Japan. The five most common motifs are wisteria, paulownia, hawk feathers, flowering quince and creeping woodsorrel. Crests still appear on formal kimono, shop curtains, temple roof tiles and gravestones.
Their design principle is exactly what the game tests. A crest had to stay readable as a small, single-colour badge, so designers relied on strong silhouettes, symmetry and a small number of parts. That is why hard mode can drop colour entirely and still be fair: the crests were made for it.
Kamon exercises visual discrimination, telling similar shapes apart quickly, and on hard mode it adds visual working memory, because you must hold the positions of hidden crests you uncovered earlier. It is the most attention-heavy of the three stacking games in MyRin. For more on how attention training works, and what it can and cannot do, see attention training in MyRin.
For the culture behind the other MyRin games, the free ebook The Mind Games of Japan covers them chapter by chapter. MyRin is free on iOS and Android with 30 games and 18,000 levels; the full list is on the MyRin games page.
Tap a lacquer stand to lift its top crest, then tap another stand to place it. A crest can only land on an empty stand or on an identical crest. The level is solved when every crest of a kind sits together on one stand. On easy and medium each crest has its own colour; on hard all of them are gold.
Read them by outline instead of colour. Sakura has five round petals, kikyo is a five-pointed star, uroko is three triangles and yotsume is four diamonds. The pointed crests, kikyo and uroko, are the fastest to recognise and make good anchors for the rest of the board.
A kamon is a Japanese family crest. Crests came into use among the aristocracy around the tenth century, spread to warrior families and later to commoners, and today an estimated 20,000 to 25,000 are in use in Japan. They still appear on formal kimono, shops, temples and gravestones.
All three use the same stacking rules. Hue sorts coloured balls, Temari sorts thread balls with traditional colour names, and Kamon sorts crests, dropping colour on hard mode entirely. That makes Kamon the purest test of shape recognition of the three.
