A small step forward for those already doing well in math. Designed to gently increase everyday engagement. For learners who are already comfortable with basic calculations, the challenge is often not ability, but consistency. In this app, correct answers drive progress in battle. Fast-paced play encourages repeated exposure to similar problems — without feeling like practice. Some families describe experiences like these: “Speed improved naturally over time.” “Addition became something they felt good about.” “They stay engaged, solving along with the rhythm during shared play.” You can also record familiar voices as encouragement, creating a comfortable and focused environment. With online shared battles, it becomes something you do together — not something you assign. No pressure. No forcing. Just small, repeated moments built into everyday routines. ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Kazumon Pro | $2.99 | one-time | ## Version history (last 5 releases) ### 2.9 — 2026-06-23 New: "Friend Slime" hint system Tap the digits in a problem to bring out friend slimes that show the count. Tens-place digit calls a big slime (worth 10), ones-place summons small slimes. Ten small slimes merge into one big slime with a fun celebration. Each problem uses 1 charm. Solve 3 problems in a row without hints to earn +1 charm. The timer pauses while a hint is active — count at your own pace. Math that grows with your child Floors 1-5 now ramp up gradually based on speed and accuracy. Solve fast → step up a little. Slip up → 2 steps easier. No more sudden jumps from "1+2" to "5+4". More satisfying score animations The score now rolls up digit by digit like a slot machine, with synced coin sounds and a sparkle finish. Defeated enemies drop golden coins that fly into your score.
