How scoring works
Everything that decides a coin is computed on our server, never in your browser.
Sudoku
Solving a daily board pays coins by difficulty: easy 5, medium 10, hard 20. Practice boards are free to play and pay nothing, so you can learn a technique without burning your daily allowance.
Difficulty is not "how many numbers are filled in". When a board is generated we measure how much backtracking a solver needs to finish it, and only accept it if it lands in the right range — a 55-step board and a 3,220-step board are not the same puzzle, even if both are labelled hard.
Nonogram
Solve the picture: easy 5, medium 10, hard 15. Every puzzle is generated to have exactly one solution, so a correct deduction is never marked wrong because a second answer existed.
Memory match
Clear the board: easy 5, medium 10, hard 15. An abandoned board pays nothing — only a full clear counts.
Minesweeper
Clear every safe square: easy 5, medium 10, hard 15. Hit a mine and the field is lost — no coins, but no penalty either. Your first dig is always safe, because the minefield is built around it.
Word search
Find every hidden word to finish: easy 5, medium 10, hard 15. Partial finds pay nothing, so the reward is for a finished grid rather than for poking at it — but nothing is lost either, since the puzzle stays open until you have them all.
2048
Coins follow the highest tile you reach: 128 → 5, 256 → 8, 512 → 12, 1024 → 16, 2048 → 20. Merge higher and you still get 20 — the cap is deliberate, so a lucky run cannot out-earn a day's play.
The daily cap
You can earn up to 25 coins a day. Once you hit the cap, games still play and still count, but they pay nothing until tomorrow (midnight, Philippine time). The cap keeps the game honest for everyone: it removes any reason to automate play.
Why the server decides
A sudoku solution is checked against the solution stored with the board, and a word search is checked against the cells the server placed each word in. A 2048 game is checked by replaying your moves from the seed we dealt — every new tile comes from that seed, so the server can reproduce your exact board and score. If the replay does not agree with what your page shows, nothing is awarded.
The practical consequence: editing the page, the score, or the board changes nothing. Only moves are accepted, and only a move log that the server can reproduce pays out.
What coins are not
Coins are a game reward. They are not money, they cannot be transferred to another player, and they cannot be cashed out. Boosters and cosmetics that spend them arrive in a later release.
