GG567Echo

GG567Echo is a calm, offline single-player memory game. Four large keys stand on a two-by-two stage, and every key has its own color, shape, texture, letter code and optional tone. Because no two keys look alike, you never have to rely on color alone.

How it works
Each round a sequence of keys lights up one after another. Watch the order, then repeat it by tapping the keys in the same order. Clear the round and the sequence grows by one step. Make three mistakes and the session ends.

Three ways to play
Classic: repeat the sequence exactly as it lit up.
Reverse: enter the sequence from the last light back to the first.
Gap: one step is hidden during the demonstration, so you fill it in from the candidates.

Built to help you improve
A mistake instantly shows the wrong key and the correct symbol, then replays the demonstration up to the point before your error, so every failure is a chance to learn. If you need another look, you may replay the full demonstration once per round, with a reduced score for that round.

Clear scoring
Clearing a round of length N awards N times 10 points. Consecutive cleared rounds add a streak bonus of up to 100 percent, and using the replay halves the points for that round. The full scoring rules are always available in the play guide.

Daily challenge
Every day you get a fixed set of rounds derived from the local date. Practise them as often as you like during the day, and only the highest score is kept.

Your progress stays on your device
Highest scores, longest sequences, the last ten rounds and frequent mistake positions are saved for each mode. There is no account, no internet connection, no ads and no tracking. All data stays in private local storage on your phone.

Settings
Adjust sound effects, vibration, demonstration speed, graphic symbols, symbol size, theme and reduced motion to match your preferences. Keys stay clearly visible even when the sound is off.
