Is Onyx Ephemeris really free?
Yes, completely free. You can play all modes and grids without paying anything.
Does it work offline?
Absolutely. Once installed, the game runs entirely on your device with no internet needed.
What's the hardest grid size?
The maximum grid is 8×8 (64 tiles total), which offers a serious challenge even for memory enthusiasts.
Can I sync progress across devices?
Cloud sync is available with optional account linking, so your progress travels with you.
Look for patterns in the first few flips. Symbols often cluster in visual zones on the grid—use that to your advantage.
Start with smaller grids to build confidence. Master 4×4 before jumping to 6×6 or 8×8.
Create a mental map as you play. Position matters—remember that the circle is top-left, the star is middle-right.
Don't rush. Slower, deliberate flips lead to better memory encoding than quick, chaotic taps.
Play during your peak focus hours. Memory games shine when your mind is fresh and alert.
