No Duel!
Read full descriptionHide full description
One cowboy per territory. No duels allowed. No Duel! is a cozy logic puzzle where every placement matters. Place exactly one cowboy in each colored territory without letting two cowboys see each other horizontally or vertically, and never place them on neighboring tiles. Love Queens, Star Battle or Two Not Touch puzzles? No Duel! gives that classic grid logic a Wild West twist: crates block the line of sight. Study the board, use every obstacle, and find the unique arrangement that prevents every duel. SIMPLE, TACTILE RULES Tap a tile to mark it with an X, place a cowboy, or clear it. An interactive guided tutorial introduces every rule before letting you solve each puzzle your own way. OVER 1,000 LOGIC PUZZLES Progress through a campaign with a smooth difficulty curve, no timer, no lives to lose, and no energy to wait for. Every board has a single solution you can reach by logic alone, without guessing. Take your time and continue whenever you want, even offline. A DAILY PUZZLE Return each day for a new board and keep your streak alive. Daily puzzles use the same rules as the campaign, so only your logic makes the difference. MEET YOUR COWBOY CREW Unlock new characters as you progress, discover their personalities, and equip your favorite. Sheriff, Jessie, Silas and the rest of the crew come to life throughout the game and react to your decisions. NEED A HAND? Assist highlights a logical deduction without solving the entire board. Reveal can place a correct cowboy whenever you want help moving forward. No Duel! is available in English and French. The game contains optional rewarded ads and occasional ads between selected levels. A one-time No Ads purchase removes them and unlocks the Rebel. No subscription is required. Place the whole crew. Prevent every duel.
