A hundred chess levels against the AI, beginner to club player
A hundred chess levels, and the opponent gets stronger with every one of
them. Click a piece and every move it may make lights up; click a lit
square and the piece goes there.
It starts gently. On the first levels the opponent plays with a handicap —
without a queen, without knights, or with nothing but a king and pawns — so
a first game is winnable. From there the strength climbs level by level,
from around 150 ELO to 1900, and every stage of ten levels brings a board
of its own: pine, olive, walnut, marble, ink, emerald, plum, graphite,
glass and obsidian.
There is help for every skill level. A hint button suggests a good move,
your own pieces blink red when they are under attack, and any move can be
taken back. Two dice decide who opens the game. Every game you win is kept
as a board you can look at again, with your time and your stars.
- A hundred levels in ten stages, each stage with its own board
- The opponent plays with a handicap on the early levels
- Every legal move of the piece you pick lights up
- A hint when you are stuck, and your threatened pieces blink
- Take back a move, turn the board, and it remembers where you stopped
- Three stars per level — win in fewer moves to earn them
- A gallery of every game you have won
- Music and sound each with their own volume
- Mouse and keyboard
Available in 22 languages.
