The longer your max combo is, the more coins you get you get, and it goes exponentially :
with 100 you get only 45,
with 500 you get 385 coins,
with 1000 you get 1260 coins,
with 5000 you get 26260 coins,
with 10000 you get 102510 coins,
with 14700(personal best) I got 219775 combo-based coins !
And I didn't even count the coins you pick up on your way…
Got it ? So never ever break that chain if your goal is wealth !
Want some cool tips for the harder levels ? First forget abour symetry, put all your weapons and gathering droids on one side and all your defensive sets on the other side. Then all you have to do is to clutch yourself to the wall. you'll encounter less ennemies and won't show your defensive sets as targets !
