ISLAND ROUTE: 1-2-1-3-4-5-1-2-3
There are a few ground rules for running this category. Two things are important here; the first being upgrading the home base every time it's off cooldown, and the second important thing is to rush the cliff portal. Nothing else matters. Here's a quick 10 point guide to actually running every island:
1 - Go to the centre of the island as soon as you land, hire the two blokes in the centre of it. 2 - Hire one builder man and one archer out of the two vagrants, in the order archer-builder. 3 - Run all the way to the left of the island, hiring and remote hiring(1) everyone while paying off the greed wave.(2) 4 - Pick up all coins on the way there, then the gems on the way back. IMPORTANT - we do not need many gems for this run, so if you are on island 2 you need EVERY chest. Island 4 you need 1 chest and island 5 you need 1/2 chests, depending on whether you want the unicorn or not. I would recommend it, but if you don't end up using it then it's still faster to stay on griffin. 5 - Do the same for the right hand side - make sure you remember which side the cliff portal is on! 6 - Upgrade the camp as fast as possible, try to get 1 as soon as you start on the island and then one when you have gone down one side of the island. If you want extra efficiency, use the later upgrades of the camp (which have a longer cooldown) to explore, and cut trees down on the first few days. 7 - Continue to amass wealth and hire archers, leave 1 villager without a job in your base for the knight upgrade (assuming you brought knights from previous islands). Make sure they are both on the cliff portal side! 8 - If you have 2 knights on the right side, and plenty of archers for them and basic defence on the other side, you are ready to assault. The bomb costs 20 coins, going into the portal takes 5 coins and blowing the bomb takes 5 coins. Make sure you have a full purse of cash (not gems!) for the attack. What comes next is rushing the portal(3). 9 - Once you make it out, start investing money by putting it all into trees, or banking. Banking gives interest at a maximum of 8 coins a day (100 coins in the bank) or 7% up to 100 coins. Trees are a more active way of making money, since you can try to double the money on any given tree, but it takes up builders time, which is needed to build the boat. 10 - Sail away!
Now, time for some glossary stuff:
(1) Remote hiring is leaving a coin in the camp. From what I have noticed, there is usually a vagrant spawn every morning and evening, something like that. Generally 1 coin will do the trick, saves a lot of time when hiring in the future.
(2) Paying off the wave is probably the most important feature of this run. All it involves is giving the greed some coins to allow your monarch to continue travelling and to also allow any villagers to get to the base. I don't know entirely now many there are on each wave, perhaps someone could count, but the important ones are as follows:
ISLAND 1
DAY 1 - 2 GREEDLING DAY 2 - 3 GREEDLING ISLAND 2 DAY 1 - 1 GREEDLING
After this, you should be able to do it by seeing how many there are.
(3) Portal rushing is much simpler that it seems on paper. By the point you start doing this, you are on island 4 - this means 3 portals to take out and 1 cliff portal with 4 spawners in it. What you need to do is run ahead of the knights who you are leading, then lead them to the portal. Make sure the knights are attacking the portal as well. They should take out the portal in 1 or 2 greedling spawns. The counterattack wave comes now, either on your side or the other side. either way, you rush ahead to see the next portal, if it's coming your side hide behind the knights and stun them so that the knights can clear the wave easily. carry on doing this until you get to the cliff portal, and remember to keep your knights full health throughtout. Now you are inside the cliff portal, you need to push ahead yet again and put the knights between the first and second pillar(?) of the spawner. This will allow the archers to mostly shoot the spawner and kill it quickly whilst also shooting the greedlings. Carry on with this, keep 1 knight alive - luckily doesn't have to be both, because the archers will keep attacking the spawners if their knight dies, but try to keep both alive. After this, just light the bomb and run the hell away.
Finally, here are some tips for early islands which do not necessarily follow the same guide. start of the game, run to the camp, hire both and go left as per usual. Cut down trees closest to the left hand side, because of the kingdom logo it will extend really far, giving archers a place to hunt rabbits. You will ideally require on the left hand side 2 coin chests and the boat. if you don't get this, time to restart. Build the boat as soon as you can, takes 10 coins and you can be gone in 2 days/8 mins. There are also 3 vagrant camps, aim to pay off the waves on both left and right to get maximum hireage. If you do this, with remote hiring, you should have 3 builders and as many other archers as you can. When the boat has been built, set off as fast as possible. You should get all four archer spots taken up, ring the bell and leave.
Island 2 is much the same, just run around finding all the gem chests for island 1, get the stag asap and the scythe statue and you should be good. Build the coat asap, cut down trees, get money, leave for island 1. Next, Island 1 - go to the boat after getting griffin and archer statue and leave as fast as possible. Island 3, just build wealth and build the boat, upgrade the camp when you can because you want a fast finish. Then, island 4, you can finish the game using the guide above.
Two things - upgrading camps and rushing portal. Good luck, and have fun!
