INSIDE THE GAME

Review the reason for each move, not just the result.

Chess play and learning are described together. The official FAQ’s match history and suggested moves help organize review, while progress saving and purchase conditions remain separate.

An introduction from official sources. Installation, registration and gameplay were not performed. See the entry conditions below.

02 / DETAILA closer look at the gameplay

Read review colors and suggested moves

The FAQ describes opening match history from the profile and reviewing moves by color. Green indicates optimal moves, with yellow, orange and red for weaker choices; Show a better move offers a suggestion. This is a learning path, not a win-rate prediction.

Do not apply Android details to iOS

The official Android Play link points to the same Google Play package, which lists Android 7.0+, ads and optional purchases. 22 July 2026 is the displayed app update, not a price-update date. The observed purchase range was ¥199–¥12,700 per item. VIP describes premium features and ad removal; the range is not a VIP price, monthly charge or required spend. First screens and eligibility for Japanese iOS remain separate.

Sample notes, scoring and all reviews

Three bodies displayed by the store, not an exhaustive latest-first sample. They do not establish Japanese or iOS reception, overall dissatisfaction or current bugs. Player claims about prices, AI opponents and time requirements are not adopted as official conditions.

Positive share = positive ÷ (positive + negative) × 100, rounded to an integer. Mixed, neutral and unclear posts are counted separately. This pilot withholds scores below 5 clear verdicts and marks fewer than 30 as provisional. These editorial thresholds do not establish statistical representativeness or an error margin.

Codex classified the displayed text with recorded rationale; independent human validation has not been performed. Text sentiment is separate from store stars.

All returned displayed posts are retained in store display order, not latest-first order. Store selection and visibility introduce bias. Negative posts are retained, and quotation choices do not change the sample.

Written records returned 3 · Classified 3 · Outside the sample 0 (all displayed posts retained; none excluded for being negative)

These are Google Play displayed posts for the stated storefront. Device categories, regions and display orders are not pooled. Displayed dates do not distinguish original posting from updating. Truncated reviews are classified only from the available text.
