Help mode: Provide step-by-step explanations. --------------- Sudoku Rules: Fill in the 9x9 grid with numbers 1~9 such that each row, column, and 3x3 box contains each number exactly once. Irregular Sudoku: Each row, column, and irregularly shaped box contains no repeating digits. Killer Sudoku: Combines classic Sudoku rules with "killer cages" (dashed-line groups). Each cage shows a sum for its digits, which must also be unique within the cage. Kendoku: Fill an n x n grid with digits 1-n (no repeats per row/column). Groups marked by thick lines show a target number and operation (+, -, ×, ÷) that their digits must satisfy. If no operator is given, any operation applies. Skyscraper Sudoku: Perimeter clues showing visible building counts (taller numbers block smaller ones), while unmarked sides remain unrestricted.

If you ever wanted to play chess without looking at the board, or just improve your visualisation skills, but you don't know how to start, then EyeGambit is the App for you. It currently has multiple tools to help you train:  Board Recognition - Includes (a) Square Recognition - Get to know the board better and instantly recognise the square and what color it has. (b) Diagonal Recognition - Once you know from the position what a bishop or queen is attacking and what not, they will be less scary. (c) Move Recognition - Identify the moves you hear or see instantly. Memory - See a position or read a list of moves and then either replicate the position on the board or answer questions about the position. Piece Movement - Train the movement of each piece individually by playing a variety of minigames Lichess - You can either train lichess puzzles with the EyeGambit touch of difficulty, or connect to your Lichess account and send/accept challenges with your friends. Play Local Game - Play a game against a friend or a bot on your phone. You can still peak at the board when needed, but with time you will be able to do more moves without looking. If it gets too easy you can also play a simul against up to 8 bots Apart from the training, there is also a campaign to follow a progression to learn the skills (currently only for square recognition) More features to come!
