## What is Zukei Hunter?

■ Geometry from elementary school to high school, in one app

Zukei Hunter is a learning game about angles and area only: 65 stages from elementary plane shapes and solids to high school trigonometry, vectors and integrals.

■ Three stories, one for each age

- Kids: "Treasure Map", 23 steps. Follow one map from the beach to the treasure chest. Every step is hands-on: tear off the corners of a triangle and line them up, roll a circle and count the diameters, pour water and watch the depth. Find the rule with your fingers before reading the formula.
- Middle school: "The Measuring Journey", 21 chapters. A surveyor's field book. Move a figure, find what does not change, and test the claims of the Crow, a wandering scholar who sells formulas one town ahead.
- High school: "Orbit Lab", 9 chapters. On a newly settled planet, fix landing sites, relay towers and launch trajectories with mathematics alone: power of a point, the laws of cosines and sines, radians, circles, integrals.

Story answers use the same calculator as the main game - no multiple choice.

■ Answers can't be memorized

Every problem is generated on the spot from 30,832 distinct questions.

■ See the figure. Type the number.

A stage is 3 questions in a row with 3 hearts. A miss costs a heart; at zero you retry with new numbers. The hearts you keep become your stars.

Angles (20 stages): triangles, parallel lines, isosceles triangles, clock hands, polygons, boomerangs, folds, exterior angles, star angles, inscribed angles, tangents, constructions, triangle centers, trigonometric equations, angles between vectors, lines and planes.

Area (45 stages): rectangles, triangles, quadrilaterals, circles and sectors, roads through a field, composite shapes, the leaf, volume and surface area, nets and dice, tanks, moving shapes, similarity, cutting solids, Pythagoras, special right triangles, coordinate geometry, the lunes of Hippocrates, pyramids and cones, Euler's formula, power of a point, Ceva and Menelaus, the laws of sines and cosines, Heron's formula, vectors, radians, the equation of a circle, optimization, parabolas (the 1/6 formula), solids of revolution.

Clearing a stage unlocks the next.

■ The Gauntlet: the method changes, not just the numbers

Every cleared stage gets a 10-question Gauntlet. The difficulty and the method change with each question - around 245 methods in all. Clear all 10 for the stage's crown.

■ Net Master: nets fold into solids on the spot

Which solid does this net make? Right or wrong, you watch the net fold up into the solid. 101 nets: cubes, boxes, prisms, pyramids, the tetrahedron and octahedron, cylinders and cones - 11 nets for the cube alone. Unlocking adds a random 10-net Gauntlet and a 10-question Practice run.

■ Calculator built in

Type an expression, not just a number: × ÷ + − ( ) √ are accepted, and "= Calc" works out partial results. A malformed expression costs no heart.

■ Stuck? Watch the solution step by step

Each tap advances the solution one step: helper lines are drawn, the key part is highlighted, equal angles are marked.

■ Reasons to keep going

Ranks from Apprentice to Geometry Sage, combos that boost your score, a 3-minute Time Attack, a 3-miss Survival mode, Island Grab (race the Crow for territory over 24 islands), a Daily Shape, and stars and bests for every stage.

■ Safe to use

No ads. No network use except the purchase. No personal data collected. One-time purchase, no subscriptions.

■ What's free

The first 4 stages of each course, Time Attack (Angles), the first steps of each story, 2 islands per range, the first 8 Net Master puzzles, and the calculator, solutions, helper lines, hints, ranks and records.
One purchase unlocks the remaining 57 stages, the rest of the stories and islands, all 101 nets with the Net Master runs, every Gauntlet and all of Challenge.

## Pricing and in-app purchases

### 3/5 — 可もなく不可もなく

*2026-09-04*

漢字の振り仮名が所々間違っている。分度器(ぶんどうつわ)とか。課金ゲームならAI任せじゃなくきちんと確認して欲しい。

**Developer response:** ご指摘いただき、ありがとうございます。
ふりがなにAIは使っておりませんが、ふりがなを付与するプログラムの辞書の設定にバグがございました。大変申し訳ございません。
バグの修正を行い、1.2.2にて最新版を公開させていただきました。
お手数をおかけし、大変恐縮ですが、最新版にアップデートして再度お試しいただけますと幸いです。

Zukei Hunter now speaks English. The whole app - every stage, all three stories, Island Grab and Net Master - is available in English, with a language switch on the title screen.

### 1.4.1 — 2026-11-07

Zukei Hunter now speaks English. The whole app - every stage, all three stories, Island Grab and Net Master - is available in English, with a language switch on the title screen.

### 1.3.4 — 2026-09-16

・「たからのちず」の19話「箱を ひらく」で、展開図をひらき切ったあとに一部端末で止まってしまう不具合を直しました。19話から先に進めなくなっていた方は、更新すると続きから遊べます。
・展開図マスターの一覧のスクロールがなめらかになりました。
・「たからのちず」と「ストーリー」の地図の動きを軽くしました。

ご不便をおかけして申し訳ありませんでした。お知らせくださった方、ありがとうございます。

### 1.3.1 — 2026-09-08

1.3.1 であたらしくなったところ
・展開図マスターの 10 問つづけて解く遊びが 2 つになりました。「挑戦 10問」は 101 とおりの展開図からランダムに 10 問、「応用 10問」は展開図につながる数の問題を 10 問です。
・立体を見せて「この立体の展開図はどれ?」と 4 つから選ぶ問いを足しました。
・立体の見え方を直しました。ななめ上からの光で面の明るさが変わり、かくれた辺もうすく見えるので、平べったく見えなくなりました。
・ふりがなのまちがいを直しました。

### 1.3 — 2026-09-07

1.3 のあたらしいところ

・「展開図マスター」を足しました。展開図がどの立体になるかを当てるあそびです。当たってもまちがえても、その場で展開図が立ち上がって立体になるところが見られます(全 101 問)。
・展開図マスターには「挑戦 10問」(101 とおりからランダムに 10 問、どの立体になるかを当てる)と「応用 10問」(展開図につながる数の問題を 10 問)があります。この 2 つは買った方だけの機能です。
・たからのちずの「箱をひらく」でも、ひらいた図が箱に立ち上がるようにしました。
・「展開図と組み立て」に、さいころを転がして上の面を当てる問題と、正多面体の展開図の問題を足しました。
・「空間の三平方」に、円錐の側面をひとまわりする最短の道のりを足しました。
