About

Sum 12

Features
Read full description

Train your brain while having fun with numbers! This engaging domino game helps improve mental math skills as you strategically match pairs that add up to 12. It’s a great way for kids to practice quick addition in a playful and interactive way. Perfect for players of all ages who enjoy logic and number challenges! The goal of the game is to clear all the dominoes from the playing area. To do this, find two face-up dominoes whose values add up to 12 and select them one after the other. If their sum equals 12, they will be removed, allowing you to flip over any previously blocked dominoes. Keep in mind that a game is not always solvable, so you’ll need a mix of strategy and a bit of luck!

Arrow Flow — these arrows REALLY want out. Help them. Tap an arrow and whoosh — it bolts for the edge of the board. One catch: arrows are terrible at sharing. They bump, they block, they get in each other's way. Your job? Figure out the perfect order to set them all free. Easy to learn. Sneakily hard to master. Dangerously easy to play "just one more." THE GOOD STUFF • One tap. That's it. Your grandma could play. (She'd probably beat you.) • Buttery animations and satisfying little sounds • No timers, no stress — solve at your own sweet pace • Stuck? Grab a hint and look like a genius • Works offline, so airplane mode is fair game MEET THE ARROWS (they have personalities) • Linked Arrows — inseparable besties, they fire together • Numbered Arrows — divas who insist on going in order • Ice Arrows — frozen solid, tap to crack 'em loose • Pivots — show-offs that turn the corner on their way out • Obstacles — the grumpy blocks that ruin everyone's plans BUT WAIT, THERE'S MORE • Daily Challenge — a fresh brain-tickler every day. Win it for bonus hints and grow your streak • Streak bonus — keep winning daily and the rewards get bigger • Optional evening reminder, so your streak never slips (one nudge, no spam) • Neon theme — every arrow glows in its own color — plus more themes for every mood • iCloud sync — switch devices, keep your progress • A handy How to Play guide (no arrow left behind) • Now in English, Japanese, French, German and Spanish So go on — tap, untangle, and let it flow. Your arrows are counting on you.
