■ 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.
