About

Simple Shape Game

Features
Read full description

Simple Shape Game is a fun, colorful learning game designed for toddlers, preschoolers, and individuals with special needs! Children learn to recognize shapes and colors by tapping the correct shape when asked. EIGHT WAYS TO PLAY • Find the Shape — a friendly voice asks "Touch the Red Circle!" and your child taps the right one. No reading required. • Meet the Shapes — tap any shape to hear its name, count its sides out loud, and learn a fun fact ("A stop sign is an octagon!"). • Shadow Match — drag each shape onto its matching shadow. • Build a Picture — put shapes together to make a house, rocket, tree, car and fish. • Trace — follow the dots around a shape with a finger. • Bubble Pop — pop all the stars (or hearts, or circles…) floating by. • Match Pairs — flip cards to find matching shapes; the voice names each one. • Sticker Book — every 5 stars earns a new sticker to collect. 19 SHAPES AND 7 COLORS Circle, Square, Triangle, Rectangle, Oval, Diamond, Star, Heart, Pentagon, Hexagon, and Octagon in red, blue, yellow, green, orange, purple and pink, with clear black outlines and friendly faces that blink and smile. Expert level adds Cross, Crescent, Arrow, Pie, Trapezoid, Parallelogram, Semicircle and Decagon for kids ready for more. LEARNS FROM MISTAKES — GENTLY Tap the wrong shape and the right one wiggles and glows while the voice says "This is the Red Circle! Can you touch it?" Your child always ends on a success. Stars are never taken away — no timers, no losing, no stress. HELPFUL HINTS If your child gets stuck, the voice repeats the question and the answer gives a little wiggle. A big speaker button replays the question anytime. JOYFUL FEEDBACK Confetti, happy chimes, gentle haptics and 20 different praise phrases. ENGLISH & SPANISH Play in English or Spanish (Español), with correct Spanish grammar. FOR GROWN-UPS A parent area (protected by a simple math question) lets you pick the language, choose a level (Little 2–3, Big Kid 3–4, Expert 5+), choose which shapes to practice, and turn sound effects or vibration on and off. DESIGNED FOR SMALL HANDS Large, colorful shapes are easy to tap. Optimized for iPad, and also works great on iPhone.
