Also found that the youngest wasn’t even trying to solve the problem but just hitting random answers. **Developer response:** Hi Jedegaah , Thanks for the feedback and for bringing this to our attention. We'll update our algorithm in our next release so answers are less easy to predict. We'll also review the gameplay so there will be some kind of reward for actually getting the answers correct and not just guessing. We appreciate your comments and if you have any more or just would like to get in contact please email: apps@kidd.co Thanks again - The Ibbleobble team. ### 2/5 — The answer is just the lowest number! *2019-06-12* Great app, kids did love it, but then they worked out the answer was always the lowest number and stopped doing any math! If they mix this up will be great ### 5/5 — Ding ding - another great app in Ibbleobble series *2016-03-31* Just as fab as the rest, the design is sleek and perfect for children to make their way into the world of subtraction! I sat with the kids and help on the no timed section and built up to let them try beat their high scores on the timed levels! ### 5/5 — Great for beginners *2015-12-26* Fun too! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
