Crack the Pattern: Math Puzzle

"Oh — that's it."

Crack the Pattern is a math brain puzzle built entirely around that one moment.

Move a single matchstick. Flip a neon segment. Find the relation hiding between six numbers.

Eighteen kinds of puzzle, laid out along a single path, with exactly one thing to do next.

■ Nothing to choose

There is one button on the home screen: Continue.

Past the 1,000 campaign stages, the same generator keeps going — endlessly.

A small hurdle every 10 stages and a boss gate every 50 keep the curve from flattening out.

Every board is generated fresh. Memorized answers get you nowhere.

■ Eighteen kinds of puzzle

Arithmetic & sequences

· Calculation — four operations and order of evaluation

· Sequences — 22 rules, from arithmetic and geometric to Fibonacci, Collatz, primes and pi

· Operator quiz — drop in the missing operators to make the equation true

· Rule deduction — 68 rules; find the relation hidden between two numbers

· Quads · number walls · multiplication tables · spokes

Building & construction

· Build — make the target number out of the pieces you are given

· Cross-math — ten boards where every row and every column has to hold

· Magic squares — ten boards: square, triangular, cross, hexagonal

· Slide boards — push tiles around until the equations line up

· Matchsticks — move one stick to repair a false equation

· Neon — rotate, flip and join glowing segments into an equation

· Hidden — work out the number each shape stands for

Visual & spatial

· Area — 32 figures; cut and recombine to find the area

· Counting — 32 arrangements; you have to count what you cannot see

· Transforms — rotation and reflection; pick the result

■ Local versus — same wifi, same puzzles, at once

Two to four friends solve the exact same boards at the same time.

Whoever solves the most before the clock runs out wins.

Create a room and you get a four-character code; it shows up on every screen on the same wifi.

No internet, no server, no sign-in — the phones talk to each other directly.

Three difficulty tiers, and 5 boards in 2 min, 10 in 4, or 15 in 6.

Stuck on a board? Pass it — but a pass still uses up one of your boards.

No hints in versus. What you are racing on is noticing first.

■ Weekly rankings

Your best 30 stages of the week add up to your score for that week.

You are placed with thirty players of similar skill, and every Monday the group splits up

and down. Playing well moves you, not playing long.

■ Being stuck is not the end

· No timer. No penalty for a wrong answer. Retry as often as you like.

· A hint never hands you the answer — it shows the first step, as one line of math.

· Still stuck? Skip it and move on. Skipped stages are remembered and come back later.

■ At your own pace

Pick one of three profiles when you start: easy and light, for puzzle lovers, or a real

challenge. The same stage 500 is a different board depending on which you chose, and XP

follows that difficulty — solve faster, chain correct answers, take on harder boards, earn more.

Set a daily goal of 5, 10, 15 or 20 stages and clearing it pays a bonus.

■ Works offline

On the train, on a plane, exactly the same. Progress is stored on your device.

No account, no sign-up.

■ English and Korean

The app starts in your device language and you can switch any time in Profile.

■ Ads, and getting rid of them

An interstitial appears now and then between stages, and there is a banner at the top.

Hints and skips are opened with a short rewarded ad.

If the ads get in the way, one in-app purchase removes them — forced ads only, unlimited

hints and skips, or both. It is a one-time purchase, and it restores on a new device.

■ Made for

· Adults who like math and logic puzzles

· Anyone who wants a short, sharp mental workout

· Anyone with a friend sitting right next to them

Whoever spots the hidden rule first wins.
