Explore the Solar System in Planet Formula, a match-3 puzzle game featuring 125 unique levels with engaging objectives. Complete each level by earning points, breaking ice tiles, or collecting coins—all within a set number of moves. Earn special power-ups: - Magic Planets: Match five planets in a row or column to create a magic planet. Swap it to clear all planets of the same type on the board and score big. - Special Planets: Match four planets to create a special planet with a white border. Use it in a match to clear an entire row or column. - Discover combinations like T-chains and L-chains for massive point boosts. Break ice by clearing planets underneath, and remove walls by eliminating adjacent planets. Be strategic — walls grow if no nearby planets are destroyed in the previous move. Accessibility Features: Planet Formula is designed with VoiceOver users in mind: - Tap a grid cell to hear the planet’s type and position. - To move a planet, select it with a single tap, then double-tap to start moving. - Choose the destination with another tap and confirm with a double-tap to complete the move. With simple mechanics and thoughtful design, Planet Formula offers an enjoyable, relaxing experience — perfect for playing at home, during a break, or while commuting. Challenge yourself, earn points, and rise through the ranks in this solar system-inspired puzzle adventure.
Block Blast
Read full descriptionHide full description
A block puzzle built so that every piece of information reaches you three ways at once - visual, audio and haptic. Lose any one of those channels and the board is still fully readable, and still fully playable. Eight by eight grid. Three pieces at a time. Fill a row or a column to clear it. THE IDEA • Colour is never the only signal. All seven block colours carry a distinct pattern - dots, horizontal stripes, vertical stripes, crosshatch, diagonals, checkerboard, waves - and the pattern is always drawn, never an opt-in extra. • The board can be heard. Every cell has a pitch from its row and a place in space from its column, rendered through a spatial audio environment. Scan by ear and build a map of the board. • Nothing requires dragging. Drag, tap-tap and dwell all drive the same game state, so you can switch between them in the middle of a run. • Mistakes are cheap. Undo is earned as you play, near-misses snap to a legal spot, and Zen mode has no game over at all. BLIND AND LOW VISION Every cell and every tray slot is a labelled VoiceOver element: "Row 3, column 5, red with dots, fits here, clears 2 lines." Piece descriptions lead with size, because size is what decides whether a piece still fits. Audio explore turns the board into a direct-touch surface: drag a finger to hear each cell as you cross it, lift to hear it described, triple-tap to place the piece in hand. This is the mode for playing with Screen Curtain on. Every sound is synthesised on your device as it plays, so the pitch mapping used for navigation stays exact. COLOUR BLIND Seven colours, seven patterns, always drawn. Deuteranopia, protanopia, tritanopia and achromatopsia simulation can be switched on for the whole game rather than a preview swatch, so you can check a palette in the situation you actually play in. Block borders thicken automatically under Increase Contrast, and a block key lists every colour with its pattern name. MOTOR AND SWITCH CONTROL • Drag and drop - the piece floats above your finger and a near-miss snaps to a legal spot. • Sticky drag - tap a piece, every legal landing spot lights up, tap one. • Dwell control - tap a piece, rest on a cell, and it places itself. Works with Switch Control, adjustable from 0.4 to 4 seconds. Plus optional confirm-before-placing, full Reduce Motion support, and a one-tap maximum accessibility preset that sets high contrast, patterns, tap-to-place, spatial audio, haptics and verbose speech together. HAPTICS A looping heartbeat while a piece is in hand, a sharp tick when it crosses a cell where it fits, a dull thud where it does not, and a burst that grows with the number of lines cleared. MAKE IT YOURS • Six themes: Classic, Neon Glow, Pastel Soft, High Contrast, Nature, and Minimal - which paints every block the same white, because pattern carries all the identity a block needs. • Four sound packs: Synthetic, Organic, Retro and Nature. • Four clear effects, three levels of speech detail, and score announcements on or off. TWO MODES Classic keeps score, grows a combo up to five times over, and ends when nothing fits. Zen never ends - when no piece fits, the fullest rows dissolve and play carries on. PRIVACY No accounts. No ads. No analytics. No network calls of any kind. Your settings and your best score stay on your device, and nothing else is ever collected. English and Indonesian throughout, including VoiceOver labels and spoken feedback. Siri knows both: "Start Block Blast" and "Mulai Block Blast". I kept the app's British spelling ("colour") since that's what the UI strings use. If you'd rather match US storefront convention, swap to "color" in the description — the keyword field already uses "colorblind".

Verdict
The clearest difference is in-app purchases: Block Blast at none against Planet Formula's 3. Block Blast also leads on ads (none vs shown). Planet Formula's advantage is device support (4 vs 2) and iOS requirement (13.0 vs 18.0). On price there is nothing between them.
