Stamps is a puzzle game where you arrange stamps in a grid to achieve goals related to their country, contents, and cost. All stamps from the same country follow the same rule when placed, influencing the board by moving, removing, or swapping with other stamps. Careful planning lets you turn those rules to your advantage, but neglect them, and they’ll disrupt your plans. Every game you are given 4 random country stamps and you must advance through 5 stages of randomly chosen goals. The number of goals you need to meet increases in later stages, making the game progressively harder. What's included in the demo?

Access to all 10 stamp sets, hand crafted puzzles, adjustable difficulty, a daily mode and stats.
