CrazyStone DeepLearning

CrazyStone DeepLearning is a focused Go study and practice app that combines neural-network based evaluation with Monte Carlo Tree Search to offer an adaptable training partner for players ranging from absolute beginners to strong amateurs. The app centers on study, analysis and repeatable practice: it supports local AI play without an internet connection, optional online human matches, certified Dan/Kyu examinations through the International AI Go Association, and import/export of SGF game files so you can review and share full game records.

Engine design and level structure

The engine in CrazyStone DeepLearning blends learned positional evaluation with probabilistic tree search to produce varied, human-like play across multiple strength settings. In the free (lite) build you get 17 adjustable AI levels, which are tuned to represent a broad progression from novice patterns up toward strong amateur play; an optional premium upgrade raises the top level to deeper, slower analysis for players who want extended tactical depth. Levels emphasize different aspects of play — reading, shape, middle-game fighting — so repetitive practice against specific strengths yields clear areas for improvement.

Gameplay mechanics and controls

Controls are designed for clarity on phones and tablets: direct touch placement for intuitive moves, an on-screen cursor mode for precise selecting on smaller displays, and pinch-to-zoom for navigating 19x19 boards. Move speed and engine thinking time are adjustable so you can slow play for detailed study or speed up sessions for focused repetition. Undo, hint and territory overlays are available to support learning during review, while clear markers show captures, liberties and estimated territory so tactical patterns are easier to recognize at a glance.

Progression, rating and challenge systems

A built-in Rating Mode records wins, losses and detailed game history so you can monitor improvement across board sizes and time controls. Rating Mode features unlock gradually as you reach higher in-app ratings, providing structured milestones for study. For formal evaluation the app integrates certified Dan/Kyu tests administered by the International AI Go Association; these assessments produce certificate images on successful completion and require an account registration for test administration and result tracking.

Study tools, SGF handling and replay value

Study is supported through reliable SGF import/export, letting you transfer games from other tools or share your records with teachers and study partners. The replay controls allow automated playback at variable speeds or manual step-through move-by-move, and you can copy game data to the clipboard for use in external study materials. Combined with configurable handicap settings and komi adjustments, these features give players many repeatable practice scenarios that sustain long-term engagement.

Rule sets, board sizes and scoring

CrazyStone DeepLearning supports 9x9, 13x13 and 19x19 board sizes and offers both Japanese and Chinese rulesets, including standard territory and capture scoring modes. By adjusting board size and rules you can focus on fundamentals with smaller boards or work on full-game strategy and life-and-death for larger formats. The app displays scoring estimates and captures clearly during review to help you cross-check variations and understand endgame consequences.

Customization and accessibility

Customization options are concentrated on study needs: adjustable AI levels, configurable timing (including Byoyomi) and visual settings that improve legibility on small screens. Accessibility tools — such as adjustable move speed, hint intensity and larger move markers — make the app approachable for newcomers while advanced settings expose deeper engine options for serious students. The interface favors readable stones and clear grids so tactical reading is not obscured by clutter.

Offline practice, online play and subscription information

Offline practice against the integrated AI is fully supported for situations where you want uninterrupted study without network access, while online matchmaking connects you to human opponents when available. The app offers an optional premium subscription that removes ads and unlocks the highest AI strength and additional rating features; this premium plan is a monthly, auto-renewing subscription with standard platform cancellation policies that require you to cancel before the next billing period to avoid renewal. Overall, CrazyStone DeepLearning aims to provide a reliable platform for steady improvement, repeatable drills and verifiable certification paths for players working through the ranks.
