CONTENTS -------- Purpose Description Train a sudoku strategy Get the next strategy for continuation Get the next value for continuation Supported sudoku strategies Installation Starting SudokuTrainer Display the documentation Restrictions PURPOSE ------- This document informs about SudokuTrainer version 0.01.5. DESCRIPTION ----------- SudokuTrainer applies a series of sudoku strategies to find a continuation in solving the user's sudoku game, starting with the easiest strategies. The user may pause this process at various events to see what SudokuTrainer has achieved. SudokuTrainer may help the user in three areas: - Train a certain sudoku strategy - See which strategy is used in the current state of the game - Get a new value to continue solving the game Each of these usage areas has it's own documentation. Train a sudoku strategy ----------------------- The user pauses SudokuTrainer when it just found the desired strategy. At this moment the consequences of the finding are not yet shown on the visible sudoku board. So the user may try to find the strategy himself. If he isn't successful he may ask SudokuTrainer for clues. The aim is to find the strategy with minimum help. Get the next strategy for continuation -------------------------------------- All currently known values (the preset and the found) are used as the initial puzzle. The user lets run SudokuTrainer a single step. Then he may try to detect the finding, or just see all the clues at once. The game may go on. Get the next value for continuation ----------------------------------- This aid is well suited for sudoku players that don't know about strategies. All currently known values (the preset and the found) are used as the initial puzzle. The user lets pause SudokuTrainer when the next value is found. He can't see it on the visible sudoku board, so he lets run SudokuTrainer to the next value. Now the previous finding is shown (and marked) on the board. The game may go on.
