Open up IGG and summoners wars And put your monster you want to evolve in the power up circle.
Now choose the monster you want to evolve it with.
Open up IGG and search for 1 once found go back to SW and remove your monster
(Not the you want to evolve)
Now back to IGG And search for 0 once found put your monster back.
Now you should see a few options with 1 in IGG
Click the 1 then go to memory and click goto now you should see your 1 and under the 1 another number might be any number from 0-30 (let's use 5 for now)
Now that we know are monsters number is 5 time to add more in. (Use 1stars)
When you have added the other monsters in go back to memory in IGG
And scroll down the page about 27 numbers you will see your 1 again but with a different number under it change that number to 5. (Repeat this step till you fill up the evo slots with the same monster. Remember your number might not be 5 it could be any number from 0-30
