This is Jam
Read full descriptionHide full description
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?
Colorosaurus

No ads. Not one. Colorosaurus is a color-by-number game for young children, built because the alternatives interrupt every thirty seconds. WHAT'S INSIDE • 84 pictures across seven packs - dinosaurs, mandalas, stained glass, flowers, butterflies, fish, and storybook places • Three sizes, from a gentle 55 pieces up to 230 for a rainy afternoon • Surprise Me! invents a brand new picture on the spot, so it never runs out • Finished pictures are kept in a gallery to look back at MADE FOR SMALL FINGERS • Forgiving taps - landing just outside the right piece still counts • Tapping the wrong piece never punishes. Nothing is filled in; the color that piece is waiting for simply gives a friendly bounce • A hint button zooms straight to the next piece • A magic wand finishes the current color, so being stuck never means fetching a grown-up • Pinch to zoom for the tiniest pieces • Progress saves by itself - put it down mid-picture and pick it up days later QUIET BY DESIGN • No advertising of any kind • No in-app purchases • No internet connection required - it works in airplane mode • No accounts, no sign-in, no email address • Nothing is collected and nothing leaves the device SOUND WORTH LISTENING TO Every piece plays a note from a pentatonic scale, so a picture colored in any order still comes out musical. Each color has its own pitch. Finishing one plays a little flourish. All of it can be switched off in two taps. FOR PARENTS Turn on Guided Access (Settings › Accessibility) and the device stays in Colorosaurus until you enter your passcode. There is no browser, no store, and no way out of the app — so it is genuinely safe to hand over. Works on iPhone and iPad. Made by a dad, for his six-year-old.
