Plan your approach to Level 1525
Configuration 1 · Targets, tray management, and time-saving decisions
Your collection plan
Level 1525, Configuration 1 has a 1:45 time limit. Your targets are Ying Yang Grey × 9; Castle Yellow × 6. There are 159 objects on the board: 15 targets and 144 non-targets. Targets account for 9% of the starting objects.
Which items to distinguish
The item names also share color labels in these pairs: Castle Yellow and Snail Yellow; Castle Yellow and Hot Air Balloon Striped Yellow; Castle Yellow and Owl Yellow. Use the icon's outline as well as its color. These are recognition checks based on item names, rather than a claim that every pair looks equally similar on the board.
Where to focus your opening
Ying Yang Grey represents 9 of the 15 targets, so it deserves repeated attention during your scans. Take a complete visible triple of another target when it is available, but return to this larger workload after each clear. Avoid filling the tray with one object from every target type.
Non-targets make up 91% of this configuration (144 objects). When targets are obscured, look for finishable non-target triples that reveal them. Keep each removal purposeful: a single non-target occupies tray space without completing a set. The counts indicate a large distraction pool, but do not establish where any object is hidden.
How to use the time limit
The 15 target objects require 5 target triples. Dividing the 105-second limit by those triples gives 21.0 seconds per target triple if all time were spent on targets. This is a planning allowance, not a measured completion time; searching and clearing non-targets also use that same clock.
Use the available planning allowance for deliberate identification. A hurried wrong variant can consume tray space unnecessarily. Complete existing pairs first, then rescan for another full set; the arithmetic alone does not guarantee that the layout is easy.
