In Picture Pile you can help science solve global problems like climate change and hunger by sorting with other players picture piles! The sorting works quite similar to the popular dating app Tinder. You see an image and the game asks you a question like “Do you see tree loss over time?”. You can now answer by dragging the image to the right to say “yes” or left for “no”. In addition if you are unsure you can swipe the image down to say “maybe”.
