The strategy to win Level 75. First you split your 100 jellies into 50/50 and take over all barracks. Don't upgrade any one of those yet!!! Then you try to take over those two labs on the sides. Wait till enemy upgrades to the top then take them. But if enemy is preparing poison, immediately interrupt it. Once you got the two labs, support them with all your jellies (of course from two flakes not through middle). When the two forts next to enemy boss has 100 jellies each, take them with your lab's capture. And then wait till enemy boss just sends a batch jellies out, attack with all jellies from these two forts. Now you should have taken the enemy base. Make sure you support two forts with some jellies and interrupt all enemy's lab activity (at this point your three labs should've all been taken by enemy). Just calm down and retake them one by one. At this point, the AI is dead, they won't attack at all. You can just fill labs with jellies and retake everything!
