About Spot the Tide
Spot the Tide is a calm spot-the-difference game on a quiet shore. Two pictures of the same scene sit together. Tap a change on either one and a ring marks it on both. Find every change to clear the shore.
There is no countdown and no fail. A wrong tap shakes the scene. Three quick misses add six seconds to the time that stars use, and the note says Easy does it. Level 1 and level 2 have three large changes and a calm look takes about a minute. Level 3 and level 4 have four. From Dawn Lake onward each shore has five, through a lighthouse, a whale day, a koi pond and an ice floe.
Stars compare your time and your misses with a calm pace for that shore. Hint and Loupe are free. Daily opens one of the twelve pictures from the date on your device. Your place, including which changes you already found, is saved on your device, and soft ocean waves play until you mute them.
How to play Spot the Tide
- Look at the two pictures. On a phone they stack, one above the other. On a wide screen they sit side by side.
- Tap a change on either picture. A ring marks that spot on both, so you only have to find it once.
- Level 1 and level 2 have three changes. Level 3 and level 4 have four. From level 5 each shore has five.
- A tap on empty water is a miss. The scene shakes. Three misses within about two seconds add six seconds to the star time, and a note says “Easy does it.” You do not fail.
- There is no countdown. The clock runs while you look and pauses if you leave the tab. Stars use that time plus any miss penalty.
- Hint rings one change you have not found yet, for a few seconds. Loupe is a round magnifier on your finger for a short while. Both are free. Daily opens one shore for the date on your device.

Tips and tricks
- Sweep the picture in one slow path: sky, horizon, shore, then the corners. A moved fin is easy to skip if you jump around.
- Compare outlines before colors. A flip or a short move shows up as a shape, and a recolor shows up once the shape already matches.
- When two areas look almost the same, check the small neighbors: foam, a shell, a lily, a cloud.
- Use Hint after you have been staring. It shows one remaining change and then leaves. Drag Loupe across a patch you can almost see.
- Do not rapid-tap the water. Three fast misses cost six seconds. One careful miss does not.
- Replay keeps the same picture. Your best stars for that shore stay on the level list.
