There is literally no reason to spend money on this game. Just get the special dinos at the park. Get ones that pop up near you. Fight in the arena so you have an incubator every minute of the day if you can. try to get an hour or 12 hour prior to sleeping. Get 10 treasure chests per day for 25000. and if you want to spend a crazy amount of time on this game. Get your daily coin limit from supply drops prior to chests. so 8000+ from supply drops then 25000 from treasure chests.
Bored? Not doing anything? when tapjoy free cash event happens, do a few of those. they aren’t hard and give you free cash. Use your cash to buy coins if you are running out.
My whole family does this and we are all 3500+ arena… I dont even have a legendary yet. My oldest has indominus. I am 100/200 on my indominus, and as well as close to my stegodeus. Those will be my first 2 legendaries super close on both of them.
No reason to spend money if you dont want to be in the top 5% of the players. Im happy at being in the top 15% or so while not paying for anything
