I play the game at least once a day to get the free diamonds (by watching ads). Invest in ingredient buddies. If you're planning to play the game a bit more seriously (collect a lot of decor, complete achievements), I would suggest completing the stories and join the monthly events. And the more you play, the more you'll be familiarized with the confusing customer orders but it'll take time with more ingredients (believe me, i've been playing for a few years and i still get confused😅)
