## What is Math 4x4?

Swipe cells to add and subtract numbers — collect the target before you run out of moves or time. A simple mechanic hiding a real brain workout.

Swipe a cell and its number is added to its neighbor (right or up) or subtracted from it (left or down). Your task: collect the target number in the required amount of cells. Sounds easy? Try it against a 60-second clock or with a strict move limit.

SIX GAME MODES
• Classic — no timer, solve at your own pace
• Timed — score as much as you can in 60 seconds; every solved task adds time
• Move limit — solve within a set number of swipes and earn a bonus for moves saved
• No minus — cells can never go below zero: fewer options, deeper thinking
• Cascade — the board carries over between tasks and slowly gets trickier
• Kids — a 3×3 board with small numbers: first math for young players

THREE DIFFICULTY LEVELS
From 1–5 cells on Normal up to 11–15 on Veteran. Harder levels and modes pay more: score multipliers up to ×2.8 per task.

SCORING & GAME CENTER
Every mode earns points — for bigger targets, for solving streaks, for saved moves. Compete worldwide on two leaderboards: total score and best timed round.

AND MORE
• 5 visual themes: Steel, Parchment, Noir, Forest and Frost
• 26 interface languages
• Continue your game right where you left off
• Works fully offline

A great brain warm-up for the commute, a fun way for school kids to sharpen their math, and a calm puzzle before bed. One minute — one task. How many can you collect?


## Version history (last 4 releases)

### 2.0 — 2026-07-28

We rebuilt the game almost from scratch — the biggest update in its history. 

It all starts with a brand-new home screen: choose HOW you want to play — and go.

• Six modes for every mood: calm Classic, heart-pounding 60-second Timed, tricky Move limit, strict No minus, endless Cascade — and a Kids mode on a 3×3 board for the whole family
• Points for everything now: collected numbers, no-miss streaks, saved moves. The harder the mode, the fatter the multiplier
• Game Center: compete worldwide for total score and best round
• Five themes — from noble Steel to cozy Parchment
• The game speaks 26 languages
• Left mid-game? The Continue button brings everything back
• Board numbers shuffle every time — no two games are alike
• Cells feel alive: animations, haptics, glowing collected cells
• And yes — we caught that pesky bug where a swipe could accidentally throw you off the board. Never again!

### 1.2 — 2024-12-06
