Halfchess
Read full descriptionHide full description
Halfchess is real chess on a smaller board. Fewer squares to scan means the winning idea is easier to spot, and a puzzle fits in a spare minute. The puzzles are derived from real grandmaster games. We take the sharpest moments and rebuild them on smaller boards, most often 6x6, keeping only the pieces that matter. WHAT'S INSIDE • Checkmate puzzles, from mate in 1 up to mate in 3 • Tactics and endgame positions built around a few key pieces • A daily challenge against the computer, and a streak to keep going • Practice that adjusts to how you're solving • Works offline • Every piece stays in view, with the same rules you already know Solve as many puzzles as you like, and take on one daily challenge each day. It fits a bus ride or the gap between meetings. Free to download and start. https://halfchess.com
