Quit before addiction sets in……because once you get to the high levels, the algorithm is set so that the game becomes "pay to win". 80% of levels above 16000 become so impossibly difficult, you must pay 10 gold bars to get past them. The rewards are a joke; mostly 5 min, because the algorithm is so ridiculous UNLESS YOU GO AND BUY MORE GOLD, OR "Packs' you will continue to get IMPOSSIBLE BOARD. But then miraculously, after you spend $$$, suddenly what was impossible is done with moves left. Just sayin'. ….King Games has take the fun out when you already know if you do not spend $$ you simply will remain STUCK.😡 GREED is the only constant.
