LastOneLost vs Sparkora

Can you beat the AI at its own game? LastOneLost is a classic Nim strategy game — deceptively simple, endlessly deep. Take matches from the table, but beware: the player who takes the last one loses. One wrong move and it's over. Can you find the winning strategy? HOW TO PLAY: The table starts with matches arranged in rows. On each turn, take any number of matches from a single row. Force your opponent to take the last one — and win. FEATURES: - Challenge the AI bot or play with a friend on the same device - Customize the number of rounds to win the match - Choose from multiple board layouts - Track your stats and climb the leaderboard

A sum built out of matchsticks that does not add up. Move exactly one match and it does. That is the whole game — and the moment you finally see it, it looks obvious. 6 + 4 = 4 is wrong. Lift one match off the six, lay it back down, and suddenly it reads 0 + 4 = 4. No trial and error, no luck: just the small click in your head when the answer arrives.
