Checkers — draughts outside North America — is a deceptively deep game on an eight-by-eight board. Pieces move diagonally forward and capture by jumping, and a piece reaching the far row is crowned a king that can move backward too.
This version plays English/American rules, where kings move one square at a time rather than flying like a bishop. Captures are compulsory, which is what makes the game about forcing sequences rather than avoiding them.
In standard English/American rules, yes — if a capture is available you must take it. That's what makes sacrificing a piece to force a winning sequence a core tactic.
Move and capture diagonally in both directions rather than only forward. In these rules a king still moves one square at a time — there are no flying kings.
Yes — tap a piece then its destination. Nothing to install.
