Bubbly Primes is a non-violent game, with no ads, and no in-app purchases. Once installed, it also doesn’t require internet access — it’s an offline game. - “A really fun game that teaches kids about prime numbers and factoring,” - The Parenting Beyond Discipline podcast. ~~~~~~~~~ How To Play For a video, search for “How To Play Bubbly Primes”. It really only takes a few seconds to figure out the basic game. - Tap “Start” to begin. - Tap bubbles that contain composite numbers (numbers you can factor). - As bubbles pop apart your score goes up. - Keep popping them until they’re broken down to prime numbers. - As prime numbers get to the top, they raise your score. - Avoid tapping prime number bubbles. If you do, they’ll darken and fall to the bottom, lowering your score. - As your score rises, playful critters appear. - You can tap critters to change what they do. - You can tap the water to make waves that move bubbles or critters. - When a non-prime “composite” number gets to the top, it turns reddish and it’s too late to factor it. - You can get rid of escaped bubbles by successfully factoring a rising bubble with the same number. - Each time you achieve a new level, all escaped bubbles will go away, and you will get points for bubbles in the water. - When five composites escape to the top, the round ends. - If your score is one of the five highest, you can enter your name, and choose a critter for its symbol. ~~~~~~~~~ Do you know the factors of 117 yet? The more you play, the more amazing your number skills will become.
