Dologi is a logic puzzle application designed for children aged 4-12: every day, a short session of 5 questions, tailored to each child’s ability, turning screen time into learning through play. Dologi is fully available on all three platforms: Android (Google Play), iPhone/iPad (App Store), and web (play.dologi.app).

PROBLEMS DOLOGI SOLVES

Children are using devices more and more, but most of the time is spent watching videos or playing quick games. Parents need something that engages their child’s mind: not too easy to get bored, not too hard to discourage, a short play session with clear stopping points.

KEY FEATURES

• Over 100 types of puzzles in 7 topics: Thinking, Patterns, Space, Mathematics, Focus, Memory, Listening. The puzzles are generated from a template, so each session is different.
• Difficulty tailored to each skill: do well, and it gets a little harder, if stuck, it lightens up; wrong answers can be tried again with step-by-step hints.
• Creative corner with 12 tools for free play: drawing board, drawing robot, music workshop, robot room (teach robots using "if... then..." rules), marble rolling, guest garden, light room, gear workshop, chess room, assembly workshop, coral bay, garden market.

WHO SHOULD USE IT

Preschool and elementary school children aged 4 to 12, along with parents who want their child to develop the habit of thinking for a few minutes each day instead of just watching videos.

DIFFERENTIATING POINTS

• Non-repetitive puzzles: generated from templates, answers verified by the machine, and the rules are based on observable characteristics of objects so children can deduce them, not guess.
• All content, illustrations, and sounds are created by the team, not copied from elsewhere.
• Respect for children: no ads, no tracking tools, no collection of identifiable data about children. The puzzles run directly on the device, progress is stored on the device, and it can be played without network access.
• Designed for tablets first: the interface uses the entire screen both horizontally and vertically, but it’s also neat on phones.
• Developed by Vietnamese, fully available in Vietnamese.
