A math game out now on the App Store, Google Play, and Mac App Store

Math that
plays like a game.

Board Together: Math Practice turns equations into a tile puzzle. You get a rack of numbers and signs, a few equations with blanks, and a short clock. Drag a tile in, the line checks itself, and the next one slides up. Play on your own, or split the rack with someone and solve together.

What a round looks like.

Four moments from real play: a solo run mid-clock, a shared board with a trade in progress, mixed-level lanes, and the summary at the end.

The idea

Tiles, blanks, a clock.

Tap a tile, drag it into a gap, complete the line. The whole game grows out of that one move. Here is the rest of it.

Ways to play

Built first for iPad. Up to two people.

Solo Rush

One player against the clock. Eight tiles in the rack, three equations to fill, five hearts, 120 seconds. Solve as many as you can, then try to beat that number next time.

Co-op Shared Board

Two people, one iPad, the same equations. You both reach into the same board, so you split the easy lines and gang up on the hard one. One score for the team.

Co-op Individual Lanes

Each player gets their own equations at their own level. A grown-up can run algebra in the top lane while a kid runs addition in the bottom one, and every solve still adds to one team total. This is the part we are proudest of.

Versus

Same split layout, separate scores. You each keep your own count and race. Set the two sides to different levels on purpose if the match needs a handicap.

Practice, no pressure

Every mode has a Practice switch that turns off the timer and the hearts and lets you exchange tiles for free. It is the gentle way in for a first game or a younger player.

Levels for every age

Pick what to practice, from counting and addition up through fractions, algebra, and a stretch into high-school and college topics. The picker calls them Level groups, so nobody feels parked in kid mode.

Real math, checked on your device

Every board is checked on your device against answers a person wrote and tested. If your line is true, it counts, even when it is not the one we expected.

Scores on your device

Scores and settings stay on your device. Reset them when you want a fresh start.

Made to be read

Write the page in one of three handwriting faces, including one that is easier to read. Bigger type and reduced motion are there for whoever wants them.

The whole point

Two people, two levels, one score.

The reason this game exists is the second player. Plenty of math apps sit a kid alone in front of a screen. Board Together puts two people next to each other and lets them play at different levels without anyone feeling left behind. Cover a lane, trade a tile, watch the team number climb. When the round ends, the summary shows what each person did and the one score you built together.

Why we built it

Built to feel like game night.

Most math apps feel like homework with a progress bar taped on. We wanted the other thing: a quick game you pick up for two minutes, play next to a kid or a friend, and actually want to run again. The math is real and it has to be right. The rest is just tiles, a clock, and the small satisfaction of dropping the last piece into place.
