so I was looking at the hankos,and I saw the hanko for putting "unique words", and as I want to get gold Hanko for all of them and I'm wondering,what is unique words
Since you can play the same word in different shiritori rounds, there's always that temptation of using the first one that comes to mind. Particularly as a beginner, you might, for example, constantly use ところ for words ending in と, so this hanko motivates you to put in the extra effort to remember you know plenty of other words that start with と (maybe some even use the bonus mora for that round!) – とおい、となり、という、とんこつ…
