Close Call: Brain Game

Close Call is a quick brain game where the closest estimate wins. See a picture or a puzzle, guess the number on a slider, and find out how close you got.

How many bubbles just flashed by? How full is the jar? How much pizza is left? Can you stop a hidden clock at exactly 5 seconds? Slide to your answer, lock it in, and watch the real answer drop onto the line. Every guess gets a pin, so you can see exactly who got closest.

There are no trivia facts to memorize. This brain game needs only a good eye, a gut feeling and a bit of quick mental math.

How it works
• A match is 5 short rounds against 1, 2 or 3 opponents.
• Estimate how many, how much, how long or what percent.
• The closest guess wins the round. Land right on the answer for a bullseye and 50 bonus points.
• The closer you are, the more you score. A fast answer adds a small speed bonus, but only when it's a good one.
• Timing rounds have no slider. Tap or hold at just the right moment instead.
• Most points after 5 rounds wins the match.

Thousands of puzzles
Count a crowd at a glance, fill a glass just as full as another, add up the dice before they hide, read a clock or a dial, share out a cake, work out the change, find the sale price, catch a rocket at the flag and much more, from counting, measuring and timing to fractions, chance and eye tricks. Each puzzle draws new numbers when it comes up, so there are thousands to play, and the game remembers what you've seen, so fresh rounds keep coming.

Three opponents to beat
Each opponent is tougher than the last. Beat one 3 times to unlock the next. They adjust to how well you're playing, so matches stay close.

Easy, Medium or Hard
Easy keeps the numbers small. Medium brings bigger numbers. Hard adds decimals and more twists, like pictures that hide fast or items that float around while you count. Switch levels any time from the home screen.

Daily challenge
Every day brings a new estimation challenge for your brain: 5 rounds, the same for every player on your level. Play it once a day, earn bonus XP, keep your day streak going and share your score.
