Exactly ten questions
Every level is a compact 10-question session with one correct answer, plausible distractors, and readable answer layouts.
Ten questions. Focused mental math.
Practice addition, subtraction, multiplication, division, multiples, and number comparisons in short timed levels with no ads or social pressure.
On the App Store since August 2025
A clear arithmetic game loop
Varied mental arithmetic
Move from core operations into multiples, how-many-multiples, highest-or-lowest prompts, and denser value-grid challenges.
Fair timed play
A short countdown starts each level, and the date-based timer pauses and resumes with the app instead of stealing time in the background.
Progress that keeps going
Fifteen authored levels
Levels 1–15 introduce operations, layouts, question types, harder numbers, and tighter timers in a deliberate progression.
Deterministic levels after 15
Generated levels continue the journey with repeatable rules, a maximum 3×3 answer grid, and protected minimum question times.
Private training history
Progress, sessions, question attempts, level summaries, and question-type stats are stored locally with SwiftData—not on a leaderboard.
A fair game, not a subscription funnel
Six retry lives free
A wrong-answer retry uses one life, and one regenerates each hour up to six. Completed levels always remain replayable, even at zero lives.
Lifetime Access
One family-shareable purchase unlocks unlimited retry lives and real advanced stats. There are no subscriptions or consumable life packs.
No ads or accounts
Core gameplay and stats stay on the iPhone with no ads, analytics SDKs, tracking, cloud sync, accounts, social graph, or leaderboards.
Maker note
Why every level stays short and replayable
Mental arithmetic benefits from repetition, but pressure should remain understandable. MathCraft uses exactly ten questions, protects minimum answer time, pauses its date-based timer with the app, and keeps completed levels replayable even when retry lives are empty. The challenge can rise without turning mistakes into a consumable purchase funnel or a public performance score.

How long is one level?
Every level contains exactly ten questions. Timers and answer layouts change with the authored or deterministic difficulty rules.
What happens after level 15?
Deterministic generated levels continue with repeatable rules, protected minimum question times, and answer grids no larger than 3×3.
Do retry lives block completed levels?
No. A wrong-answer retry uses one of six regenerating free lives, but completed levels remain replayable even at zero lives.
What does Lifetime Access add?
One family-shareable purchase unlocks unlimited retry lives and the verified advanced statistics. There are no subscriptions or consumable life packs.
Where is progress stored?
Level progress, attempts, summaries, and question-type statistics stay locally on the iPhone. There is no account, leaderboard, social graph, analytics SDK, or cloud-sync service.
