You’ll have to pay attention to all the animals that will appear on the revealed card of that round and try to remember how many of the same type you’ve seen up to that moment. How strongly do you trust your memory?
Each round you'll write down a number that, in the scoring phase, will give you as many point... but only if equal to or less than the real number of animals that have appeared up to that moment. Will you play safe or will you play on the edge to maximise your scoring?
