About this game

Five puzzle games in one app, a new workout every day, and it all works without a signal.

Brain Stack brings word, memory, math, focus and logic puzzles together under one roof — then gives you a reason to come back tomorrow.

▍THE DAILY WORKOUT
Three games, picked fresh each day, and here is the part people like: everyone in the world gets the same three. Same puzzles, same order, no internet required. Finish the set to build your streak.

▍FIVE GAMES, FIVE DIFFERENT KINDS OF THINKING

★ WORD STACK — Language
Drag across a wheel of letters to spell words and fill an interlocking crossword. Every word snaps into place. A 65-level journey across 13 chapters, a daily challenge, and a 60-second blitz. Words outside the grid still count — they pay the best rewards.

★ MEMORY GRID — Memory
A pattern flashes, then vanishes. Tap the tiles you saw. Get them all and the pattern grows; the grid climbs from 3x3 to 6x6 and the glimpse gets shorter. Three lives.

★ QUICK MATH — Calculation
Rapid-fire arithmetic against the clock. Answers get harder as you go, and a streak multiplies your score. No learning curve, just speed.

★ COLOR MATCH — Focus
The word "RED" printed in blue. Does the word match the ink? Simple to learn, genuinely hard at speed, because reading is automatic and you have to override it. Beat the clock on every single card.

★ NUMBER SEQUENCE — Logic
Find the number that comes next. Deliberately untimed, because thinking should not be rushed. 18 different pattern types across six levels of difficulty — and every answer tells you the rule behind it, so a miss teaches you something.

▍YOUR BRAIN SCORE
Each game feeds a rating for the skill it uses — Memory, Logic, Math, Focus and Language — and those combine into one Brain Score you can watch move over time. The games also read your rating and adjust, so you are never stuck replaying the tutorial.

▍PLAYS ANYWHERE
No signal, no problem. Every game, the 202,000-word dictionary, the daily workout — all of it runs on your device. On a plane, on the underground, in a basement: it just works.

▍NO ACCOUNT, NO SIGN-UP
Open the app and play. No email, no password, no profile.

▍EARN AND CUSTOMISE
Coins come from playing — never from your wallet. Spend them on hints when a puzzle has you stuck, or on tile styles to make the board yours.

▍MORE ON THE WAY
Three more games are already lined up: Odd One Out, Reflex Tap and Anagram Rush.
