Echo Vault

Watch the pattern. Hold it in your head. Then the vault asks you to remember it backwards or across a mirrored grid. Watch the numbered tiles light up, then repeat their sequence. Later chambers switch between forward, reverse and mirror recall. Each completed chamber earns 100 points per tile. Each wrong press deducts 75 points from that chamber and costs a life; a replay deducts 100 points and restarts your input sequence. Chamber scores never go below zero. Sequences grow from three to nine tiles and playback gets faster. Play a UTC daily course or generate a fresh practice run. Share the course seed with friends and save a score card after your run.

Choose a daily course or fresh practice course. Watch the tiles light up one at a time. Repeat the sequence by tapping the tiles, or using keys 1–9. Read the rule: reverse chambers require the last tile first, while mirror chambers swap the left and right columns. Clear twelve chambers. You have three lives for the whole run and one optional replay in each chamber. Click or tap numbered tiles, or use the number keys 1–9. Tiles follow reading order, left to right. Sound is optional; the numbers and highlights carry all the instructions. If playback is interrupted by switching tabs, resume to watch it again.
