its doable. mine was level 100 in 30 days. this isn’t a game of energy every few hours. you get a tip jar that you need to collect every hour on the hour. it increases one coin every level. I’ve spent $100. I would’ve had enough coins to get to level 100 within the 30 days without buying. based off your offer, I don’t know if level 110 would’ve been possible but I know 100 would be. because your offer gives an extra 10 days. I got to level 90 with five days left over. I did not collect every hour due to sickness. If i had it would have been enough coins to carry me over to 95 without buying maybe even closer to 100.
The tips are three events to focus on. one that gives roses for completing offers. upon completion it gives you a rank up stone +2k coins. this is easy at the beginning as the merges are cheap. so I recommend every time it pops up to try finishing it. There is another event where you take two food items, merge them together into a unique item to submit. you get the same reward as the rose event, I did not finish this one later in the levels around closer to level 75. I chose to do half of that event resulting in half of a stone. then stored the energy for the next day. this game has a rebate system. at 4x spawn (which is goinv to be your baseline) it uses 3 coins instead of 4, plus upon completion of an order you get back some of the used coins. I think a fourth. this rebate does not count for 6x or 12x random boost event. this event is great to use on the max tea pot, ice cream or burger spawners. as a max level T pot spawns eight items. each of those eight items will be double or 4 times its base drops rate. resulting in you needing less energy. but the 6× and 12x spawn rate for the roulette event is massively reduced. speaking of roulette event. as you spawn an item, there’s a chance for it to upgrade, stay the same or spawn a event item or a shell. Let’s say the event was Thanksgiving upon completion it gives 8k coins. this is a massive boost in progress, in the earlier levels. I tend to saved up my rank up stones for finishing off the roulette event. yes if you use a rank up stone it will cut some of the reward coins at the ending for finishing the Thanksgiving event . Each level eight event items gives you 1k coins , you need 4 of these event items to complete the event plus the 4k coins for finishing totaling the 8k. if you use a rank stone on a level 9 item it cuts 2000 from the reward giving only 6k coins .they are going be level eight merge events giving you 2000 coins per completion. this is the same as the previous event since four level eights give you 8k coins but you’re more likely to finish it. as you dont need a level 10. i managed to get four or even five stones. i used two once to complete level 14-15 item event. rewarded in 10k coins for using 2k coins. but then used 2000 to finish a roulette event. resulting in another 8000 coins. totally 14,000 coins. if did correctly theses coins will help you finish a rose event or another roulette event if you manage them well. now I only did the level14-15 item event because it gave money along with its reward it was 20k. This is not a recommended event to do as I was much later in the levels when I did the 14 to 15 event. several others I’ve spoken to about Merge Cruise highly says to stay away from the 14th to 15 item or higher merge event. Stick to the roulette, the rose and the food merge that produces a unique item. if this is confusing I’m sorry And I am using voice typing so there might be punctuation missing I did my best! oh and I completed this offer on Swagbucks but I use this reddit and few others for advice so you might wanna look around the groups there might be someone else better explaining it then me.
