We can collect 800 coins every 8 h for the next 7 days. Collection times are explained at the bottom. We start with 750 coins so we can collect 17.550 coins to spend in the tower (without coins from freebies). To participate in the temporary tournaments, we need Moon Walk Dragon which is at the very top.
These dragons are up for grabs: Moon Walk #925, Engineer #923, Lightning #175, Moon Rock #924, Saturn #199, Greenfluid #126 and Conjurer #712.
Tips:
Using the spin will cost more coins the higher you climb the tower.
You have to collect pieces for the dragons you want.
When you walk... you will only get things (gold, food, gems, orbs, dragon pieces etc) when you land on that field with the last step. So if you have three steps you will get the thing that is on the field of your third step.
You can not walk the full amount you spinned when you hit a wall or a catapult..
Chests on the map give random resource.
Check catapults properly. Some will bring you up and some will bring you down. Sometimes several floors.
You can also buy out the last piece of each dragon. Sometimes it is better to buy the last piece instead of walking back down because you missed a piece on the way up.
Pro tip:
On mobile devices you can check what spins will give before you walk. They are fixed. Load the game and go on flight mode. Walk with your coins and write down the results. Then close the game. Make sure it is not running in the background. Then connect with wifi (remove flight mode) and load again. Your progress was not saved. Your coins will be back again. That is how to find the best way to use the coins.
Maps explanation:
I could not save the map. So I had to cut it into pieces. Sorry.
Fields with numbers will give event coins.
Fields with coloured circles give orbs.
White circles with a D give either 5 orbs for Dragem or 10 for Draluxe.
How many fields a catapult will kick you is written besides the arrow.
Costs for buying out last pieces:
Engineer 160, Lightning 450, Saturn 750, Moon Rock 1000, Greenfluid 1000, Conjurer 1000.
Open the eventwindow. In the upper right corner besides the event name you see the timer .
This timer started with ....days,23hours,59minutes (on phone it doesn`t show minutes).
It will count down to 00d 00h 00m.
You have three timewindows of 8 hours every day to collect 800 eventpoints (coins).
Ignore the days , just check hours and minutes of the timer.
These are the timewindos to collect the coins:
23h59m-16h00m.
15h59m-08h00m.
07h-59m-00h00m
So you have 8 hours to collect the full amount of points. After that time a new timewindow will start and you start collection for the next 800 points. So it is possible to get ready with collecting 800 points ten minutes before the window ends and then after 10 minutes collect again 800 points because the next timewindow started. Just bring the time the timer shows in relation to the time your clock shows and you find the times for your timezone. I hope this is helpful.
Edit: Sorry. There was a mistake in my maps on floor 71 and floor 97 with the numbers on the catapults. I put new maps for these.
I also changed order. Posted maps from top to bottom.
Thanks to @Scott-Clark for the hint.
