This is Jam is a smart and satisfying puzzle game where color, space, and strategy collide! At the top of the board, color-coded buses of different sizes are waiting. At the bottom, groups of stickman passengers are ready to board. Your mission? Match every passenger group to the correct bus — but it’s not as simple as it sounds. Passengers come in different group sizes, take up different amounts of space, and block each other’s movement on the grid. Non-matching passengers must move onto the board first, turning every level into a layered grid-management puzzle. As you progress, new mechanics deepen the challenge: • Dispensers – Release passengers strategically • Hidden Passengers – Reveal them at the right time • Hidden Buses – Plan ahead without full information • Connected Passengers – Move linked groups carefully • Tight Grid Spaces – Every move matters Each level is a carefully designed “jam” where logic and planning are the only way out. Why You'll Love This is Jam: • Simple to understand, hard to master • Clean, colorful stickman visuals • Strategic grid-based movement • Increasingly complex puzzle mechanics • Satisfying problem-solving moments If you enjoy logic puzzles, spatial challenges, and clever matching mechanics, This is Jam will keep your brain busy for hours. Can you clear the grid and board every passenger?
