Pulsefield is a haptic minefield game. Drag your finger across a blank screen to find an invisible goal — guided only by what you feel. A smooth, steady vibration grows stronger as you approach the goal. A pulsing buzz warns you of hidden mines. Learn to read the signals, dodge the danger, and reach the target. No map. No hints. Just touch. Place your finger anywhere and drag. A warm, steady vibration means you're heading toward the goal — the stronger it gets, the closer you are. If the vibration starts pulsing, you're near a mine. Change direction. Trust your instincts. Reach the goal. The difficulty scales as you improve. More mines, tighter spacing, less room to breathe. Track your stats, climb the Game Center leaderboard, and unlock achievements along the way. Pulsefield turns your iPhone into a tactile puzzle. Every round is different. Every path is yours. Fully accessible with VoiceOver. No ads. No account required.
