SaioWorld - the Othello center

SaioWorld is the place for Othello/Reversi: play online, study, analyse, train and take part in tournaments. SaioWorld brings together Othello and Reversi play, analysis and training with the Saio engine developed by Romano Benedetto, three-time Italian Othello champion. PLAY AND ANALYSE • Play against Saio with adjustable thinking time or search depth, or explore positions in free mode. • Evaluate the best moves or all legal moves and consult opening-library values directly on the board. • Analyse a complete game with regressive analysis, a move-by-move report and a graph. • Edit the board, rotate positions, view the game transcript and save or load games. Copy and paste move sequences to share and study them. TRAIN AND EXPLORE • Study and memorise openings, practise middlegames and endgames, and challenge yourself in ranked training modes with difficulty levels and leaderboards. • Find endgame exercises in the WThor archive, including positions with a single non-losing move or line. • Search tournament games in WThor, inspect archive statistics on the board and simulate a player's style using archive statistics. • Explore classic openings and XOT, including XOT 2.0. PLAY ONLINE • Find opponents for rated real-time games at 1 or 5 minutes in Classic or XOT mode. • Send invitations for unrated games or play asynchronous games with 72 hours per move and optional automatic matching. • Follow ongoing games, review your game history, compare six Elo leaderboards and track your rating over time. TOURNAMENTS AND LIVE GAMES • Create and join online tournaments with automatic or manual rounds. • Organise local tournaments, manage participants, pairings and results, and choose Brightwell or Sonneborn-Berger/Buchholz tie-breaks. • Publish local tournaments online and broadcast games with authorised transmitters so other players can follow them live. LIBRARY AND PERSONALISATION • Consult the included opening library. The full library is available as an optional in-app purchase; advanced library tools support expansion and merging incremental libraries. • Choose your language and a light or dark theme in an interface designed for phones and tablets. Internet access and an account are required for online features. SaioWorld contains ads and offers in-app purchases. Support SaioWorld with an optional monthly or yearly subscription. Either plan removes the banner while active and renews automatically; manage or cancel it through Google Play. The purchase sheet shows the actual local price and billing period. Full Library is a separate one-time purchase. Subscriber recognition and additional features are planned for the future. The purchase also includes automatic access to updates of the WThor archives and other statistical data. The full-library purchase also unlocks writing moves to the library and expanding it automatically. Reusing saved evaluations speeds up subsequent regressive analyses and makes them easier to study. Separate live chats for players and spectators include emoji and personal muting. Access follows the game role and the tournament organiser’s settings.

Improved trophy notifications and progress updates, list selection, tournament round selectors, and app stability.
