Wordle

 I discovered Wordle some 7 months ago.

Explanation: simple word's game - find a 5-letter word in 6 tries.
After each try you receive confirmation - which letters you guessed in correct position  (green) and which in wrong position (yellow), it looks like that:

After 1 month I implemented a simple strategy: enter 3 words, each using different letters.
In these 3 tries I use all 6 vowels and 9 most common consonants.
In above example it was sufficient to make a guess.
Since I implemented this strategy I think my success rate is some 98%.
Failed cases were words I did not know and some obvious omissions on my side.
