The only problem I have is medium difficulty is way to easy, it goes mind-numbingly slow, but on the other hand, hard is impossible. I like the speed in which cards are placed in hard, but it slaps WAY to fast. Even if I see the combo and slap as soon as the card is placed, the computer always gets it first. Haven’t even tried the harder than hard version because hard is already impossible. It’s frustrating because I want to play fast, but I also want the possibility to win. ### 1/5 — controls? *2020-08-22* video to figure out how to slap or controls do not work. ### 1/5 — Slap *2020-04-25* I couldn’t figure out how to slap, and the computer just took all my cards. ### 1/5 — Does not render properly on a 7 plus *2018-01-07* The rules seem to be formatted for a different size. Did not get past that. ### 5/5 — Best ERS App Out There! *2013-10-14, version 1.4* Very close to the real thing. Runs perfectly. I'd like to see a feature where you can put an image from your library as your background and deck image, but other than that, it's perfect. 5 stars! Two thumbs up! ### 1/5 — POOP!! 💩💩💩 *2012-01-12, version 1.3* THIS APP IS HORRIBLE!!!! DONT WASTE $1 ON IT!! I WANT MY MONEY BACK!! CRAPP APP!! 💩💩 ### 5/5 — Better value than the dollar menu *2011-09-30* It's only 99 cents. 'nuff said. This app is testament to the many success that have come out of the project on creativity at middlebury. The old stone mill is accepting applications for funding and space! ### 4/5 — Awesome *2011-06-28* I don't get why everyone says this is bad!! The slapping works you just tap on the sides of your little area!!! I love this!!! ## Frequently asked questions about ERS ### How many players can play ERS on one device?
