Cordiko is minesweeper without the coin flip. Every grid is generated so it can be solved by logic alone, from the first tap to the last relic (here the mines are buried relics to dig around without breaking one; tags are your flags). You never have to guess.
NEW TO MINESWEEPER?
A short guided first grid teaches the one rule: each number counts the relics around it. Each new technique is shown the first time a grid needs it.
STUCK? THE HINT SHOWS ITS PROOF
The hint does not just point at a safe cell. It highlights the numbers that prove it and spells out the reasoning, so you learn the deduction instead of copying the answer.
LOST? YOU SEE WHY
Hit a relic and Cordiko shows the numbers that already proved it was there, or the move you could have proven instead. Every defeat is a lesson, never bad luck.
A DAILY GRID
The same grid for everyone on the same date, offline. Build a streak, fill your logbook, try it without a hint.
CHALLENGE A FRIEND
Every grid has a short code. Share it and a friend plays the exact same grid. 12 achievements reward proof, not luck.
FOUR FORMATS
Discovery, Classic, Large and Expert, each adding one technique: reading a number, combining two numbers, following a border, counting the relics left. Boards fit a phone, eight columns wide: Expert packs 30 relics into 8 x 14, denser than desktop Expert.
