Number Merge: Plan the Next Pair
Preserve useful pairs and create space before chasing the largest tile.

A merge is possible only when two tiles carry the same value. Before selecting anything, count the available pairs: two 2s can become a 4, but that new 4 is most useful when another 4 already exists. Thinking in pairs prevents an attractive move from producing a stranded high tile. The board is small, so every occupied square should have a likely partner or a clear role in the next two moves.
Build a short merge chain
Look for sequences such as 2+2→4 followed by 4+4→8. Complete the lower merge first only if the resulting tile can continue the chain. When several pairs are available, clear the most common low value to create room. A high-value merge may improve the score immediately, but freeing two or three spaces often creates more future options than consolidating an isolated pair.
Keep large values together
Use one side of the grid as a parking area for the largest tiles. This is a visual discipline rather than a hidden game rule: neighboring high values are easier to compare, and the remaining cells become a workspace for low-value chains. Avoid scattering equal high tiles across opposite corners, because you may spend several moves recreating the alignment you could have preserved.
Diagnose a stalled board
When no obvious pair remains, review the previous two merges. A stall usually comes from merging a value with no future partner, ignoring a low pair, or filling the workspace with unrelated numbers. Replay with one goal: keep at least one open route from 2 to 4 to 8. Track the highest stable tile and the number of useful pairs, not only the momentary score.
Return to the game with a clear method and compare like-for-like attempts.
