KALKYX is mental math transformed into a space mission, for
children aged 4 to 10.
Aboard the KALKYX station, your child is in control. ROBI, their
assistance droid, accompanies them through every calculation and never punishes them.
🛰 FOUR SECTORS TO SECURE
• ADDITIA Core — addition
• SUBTRAX Rift — subtraction
• MULTIPLEX Reactor — multiplication tables
• DIVIDIA Prism — division
⭐ A REAL JOURNEY, NOT JUST A SERIES OF EXERCISES
• 60 levels, 15 per sector, from easiest to hardest
• 12 timed boss battles, one every 5 levels
• 1 to 3 stars per level depending on success
• A brand new Quick Challenge every day, all operations mixed together
🧠 CALCULATIONS THAT REALLY MAKE YOU WORK
• Never any "+0", "×1", or "÷1": every question counts
• Numbers really do increase with each level reached
• The "7 times table" tier actually makes you review the 7 times table
• Never repeat the same question Same question in a round
• Additions and subtractions up to 1000, multiplication tables and divisions up to 12
🔥 MOTIVATION, NEVER PRESSURE
• Combos and speed boosts that multiply credits
• 14 badges to collect
• ROBI always encourages: making mistakes is part of learning
• Three difficulty levels based on age: 4-6, 6-8, and 8-10 years
👨👩👧 DESIGNED FOR FAMILIES
• Multiple children on the same device, each with their own profile and pace
• Parent area protected by a 4-digit code: playtime, number of sessions, streak of days, success rate per operation, and level achieved in each area
• Works 100% offline — in the car, on a plane, anywhere
🔒 WHAT KALKYX DOESN'T DO
• No advertising
• No data collection Data
• No account to create
For younger children, a visual aid displays numbers as
energy cells to count, and answers are provided.
Older children move on to direct calculation and a timer.
