Well, I use plenty of game resources since I do love games and my students are always enthusiastic about them. I mostly apply gamification tools to practice grammar and vocabulary. Here is my list (which is not exhaustive):
wordwall.net
baamboozle.com
learningapps.com
wheeldecide.com
online-stopwatch.com
superteacherworksheets.com/generator-word-scramble.html
https://www.visualthesaurus.com/bee/play
https://bingobaker.com/
https://www.edu-games.org/word-games/crosswords/communicative-crossword.php
https://quizizz.com/
https://quizlet.com/ (Game mode - Classic live)
Tic tac boom app
different random generators, e.g. https://www.rangen.co.uk/chars/jobgen.php
These are the ones I use regularly there are also others I come across from time to time and also build them into my teaching routine.
I've also tried https://www.classcraft.com/ru/ but not as successfully as I'd like to, feel that I have to explore it better.
