Choose a puzzle by the decision it asks you to make

Deduction: prove before revealing

Crystal Survey gives information through numbers and limited sonar. The next action should follow from constraints. If you enjoy explaining why a square is safe, start here. Progress is about reducing uncertainty; repeating a fast click sequence is not the main skill. Nonogram changes the clues to row and column runs, but also rewards distinguishing a confirmed cell from a guess.

Sliding: protect future access

Unb1ok and Tidelumo ask you to move physical pieces through constrained spaces. The key question is whether the next required standing square or lane will remain accessible. A move may look closer to the goal yet remove the only continuation. Work backward from the target and separate moving a piece from making room for it. Ice Harbor adds sliding endpoints, making a square that you pass through different from a square where you can stop.

Sorting and shot budgets

Bird Haven makes temporary space between perches valuable. Honk Heap instead limits the tray to seven slots, so starting too many triples can consume your options. Coral Rescue limits shots and allows the next colour to be swapped. These games reward checking the next pair of decisions together rather than greedily taking any visible match.

Try one opening board in each style. Compare what made you stop to think: missing information, blocked access, too little temporary space or a resource budget. That tells you more about your preference than a single universal “easy” label. No ranking here claims measured completion times or that one type is objectively better.
