Depends how many € you have and how many you would need to spend on completing the event. You will get € 10 back upon completion.

This is from a post of mine a few comment threads down, but I will edit it to fit your situation: "Providing you spend you energy wisely, you can easily clear two waves of leprechauns per hour. Then you will have a few energy left to take with you to the next hour. Having to stop zapping halfway during a wave is a waste of energy, so that is why 2 waves is the max. So that would be 14 'normal' leprechauns + 2 'last' leprechauns per hour. From those 14 normal ones you have a 15% chance of them dropping a clover, making it 2.1 clovers on average, and the last ones always drop a clover, making it 2 on average. So per hour you will get 4.1 clovers on average. If you have 35 hours left, that would average out to 143.5 clovers. So you should get the 140 you need if you play actively and not get unlucky with the drop rate."
