Hit my highest ever weekly average recently, but a bit gutted I couldn't squeeze out two more points. Had a hot streak of either getting good letters or needing to use some gems to plug the gaps and getting lucky with the random letters. Nothing new about the strategy, doubling up as many letters as possible and going for the 4 and 5 letter bonuses and it quickly adds up. A three letter word with two standard consonants and a vowel is 10 points, and you can create 8 of them by placing the letters well, which yields 80 points off the bat, plus the 5 for the daily streak. That means you only need to make up 15 points with high value letters and/or long word bonuses to score 100, which is very doable, especially considering you can easily get 6-8 extra points for adding another letter to a three letter word (2 or 4 for the extra letter, plus 4 for the +1 on each letter).
I play on just two devices, by the way. Phone and laptop. Laptop has had a mare recently, but I'm close to removing my lowest score for the week, so hopefully it'll be back in the top 10 soon.
