Jam Pillar
Read full descriptionHide full description
Unblock. Merge. Transform. Jam Pillar is a clever puzzle game where caterpillars of all shapes and sizes are jammed into a tight grid. Move them to the sorting zone — but only if their head isn’t blocked! Plan carefully: each caterpillar you move opens up new paths. Once you collect three cocoons of the same color, they merge into a beautiful butterfly. But it’s not that simple... Wooden crates hide caterpillars — destroy them by moving others nearby. Frozen caterpillars stay stuck until you complete a merge. Every move counts. Free them all and clear the board!
