How to play

A problem appears with a ring around it and four answers wait at the bottom. Every answer lays a block on your tower, coloured by how fast it came: blue for quick, yellow for slower, orange for late, and red for a wrong answer or one that ran out of time. Three red blocks on the tower at once and it falls. A red counts only while you can see it: build fifteen more blocks on top and it slides out of view, and that life comes back.

Common questions

How does the daily challenge work?

Fifteen problems, the same for everyone in the world, new every day at midnight UTC. In the daily nothing runs out and the tower cannot fall: you always play all fifteen. The ring still turns from blue to yellow to orange, and a faster answer scores more.

Only your first attempt each day counts for the ranking. The problems are the same all day, so later runs are practice — they post nothing. Tap How to play on the daily card for the rules with pictures.

What are perks?

In the campaign, five answers in a row in the blue bring a perk above the tower. Answer the next one in the blue too and it is yours; if its ring reaches yellow, it bursts.

Heart — one life back, up to three. Skip — passes a problem with no block and no fail. Time — refills the current problem’s clock. 50/50 — takes two wrong answers off the keys. Skip, Time and 50/50 wait bottom left until you tap them.

I bought Remove Ads and the ads came back

Open Settings inside the game and tap Restore purchases. Purchases are tied to your Apple Account, so this works on a new iPhone, after a reinstall, and after a restore from backup — at no extra cost.

Revives and checkpoint starts are still offered with a video after buying: those are rewards you choose to watch, not ads between runs.

My scores don’t appear on the leaderboard

Scores go through Apple Game Center, which needs you to be signed in. Check iOS Settings → Game Center. A score set while you were offline is kept and sent the next time you are connected and signed in.

Why did a problem I answered fast turn orange?

The block takes the colour the ring was showing at the moment you tapped. Harder problems — factorials, logarithms, two-step problems — get more time, so blue lasts longer on those.

Is there an iPad or Mac version?

No. Math Tower is built for iPhone and needs iOS 17 or later.

How do I delete my data?

Delete the app. Everything the game stores — scores, streaks, settings, progress — lives on your iPhone and goes with it. We hold no copy, because we have no server. Game Center scores belong to Apple; manage them through Apple’s Data and Privacy portal. The full picture is in the privacy policy.

I want a refund

Refunds for App Store purchases are handled by Apple — we never see the payment. Request one at reportaproblem.apple.com.

I found a bug, or a problem is unfair

Please tell us — a wrong answer the game marked right, a timer that feels too short, a problem that is too hard for its level. Specific examples (“5! ÷ 4 at level 17”) are the most useful.
