About

Echogrid

Features
Read full description

Place. Echo. Solve. Every tile you place echoes back a few turns later — every move is really two moves. Plan with your future self across 150 handcrafted binary puzzles, a daily challenge, and endless mode. EchoGrid is a focused logic game built around one twist: your moves repeat. Place a 0 or a 1 on the grid, and after N turns it appears again — mirrored, rotated, or shifted. Fill every cell without breaking the rules: no three of the same value in a row or column, and balanced 0s and 1s in every row and column. ► THE ECHO MECHANIC Every placement schedules a future echo. The board tells you the delay (e.g. +3 turns) and the transform (mirror, rotate, or offset). Watch the ghost circles to see where your moves will land. Plan ahead — every move is two moves. ► 150 HANDCRAFTED LEVELS Five difficulty packs from Tutorial through Expert. Each pack tightens the screws — bigger grids, longer delays, trickier transforms. Star ratings reward efficient solutions. ► DAILY ECHO One puzzle per day, the same for everyone. Build your streak and grow your garden — seedling, sprout, sapling, tree, blooming tree. Share your result with friends after you solve. ► ENDLESS MODE Wave after wave of generated puzzles with rising complexity. See how far ahead you can plan. ► HINTS + SKIPS WHEN YOU'RE STUCK Tap Hint to reveal one cell's correct value for 5 seconds — long enough to memorise, short enough to keep the satisfaction yours. Earn a free hint by watching a quick ad, or buy a 10-pack. Stuck on a level? Skip tokens unlock the next one with a single tap. ► STAR RATINGS + STATS Every level scores 1–3 stars based on how few moves you take. The Stats screen tracks your best per level — chase 3-star runs across all 150. ► CALM, FOCUSED VISUALS A clean dark theme with three unlockable palettes. No pop-ups, no clutter, no distractions — just you and the puzzle. ► OFFLINE-READY The full game works without internet. Play on flights, commutes, or anywhere quiet. HOW TO PLAY 1. Tap an empty cell, then choose 0 or 1. 2. The board shows a ghost circle where your echo will appear later. 3. Avoid creating three-in-a-row in any row or column. 4. Balance 0s and 1s within every row and column. 5. Fill the whole grid with no rule violations to win. DIFFICULTY PACKS • Tutorial — 10 levels to learn the echo • Easy — 20 levels, simple mirrors • Medium — 30 levels, longer delays • Hard — 40 levels, rotations and offsets • Expert — 50 levels, only for grid-masters Perfect for fans of Takuzu, Sudoku-lite logic, daily brain teasers, and quiet thinking games. No timers, no pressure — just satisfying logic. Free to play with optional in-app purchases for hints, skips, undos, themes, and ad removal. Designed by JK Global Gaming.
