For this you will need to complete 30 rounds of each game mode so it might be a good idea to grab a pen and piece of paper to mark off what you've done. For Standard and Unlimited this is quite easy as you need to do is fill in the Bingo word first and you can then skip straight to the next round. Repeat until you have 30 completed. For Letter Mania and Lighting this is not so simple as you will have to complete each round finishing all words. For Daily Word although you can finish the round quickly like Standard and Unlimited but you are limited to one game per day although there is a workaround. You can play this mode over and over without time glitching by changing the language in the options, and then changing back to English again.
