Erwin vs Word Tack

Erwin is a sliding puzzle played on the six faces of a cube, a unique 3D experience with spatial audio and holographic depth effects. Swipe to slide and merge tiles, or swipe the background to rotate the cube and work the other sides. Tiles have a value that doubles when they merge, and each merge adds to your score. Play long enough and quantum effects begin to appear: some tiles are in superposition, alternating between two values, some entangled and move together, and some even teleport. Play together with friends via Game Center Multiplayer: take turns on a shared cube, watch each other's moves in real time, and climb the cooperative leaderboard. Universal purchase with Family sharing: pay once, and play Erwin on iPhone, iPad, and Mac, with up to six family members. Erwin respects your privacy and your wallet. This is an app I wanted for myself without compromise or dark patterns: pay once and it's yours, on all your devices, with no ads, no nagging in-app purchases, no tracking, no profiling.

Sort 40 words into 8 groups. Swap tiles until every row of five shares something, and watch each finished row get taped down to the desk. Word Tack is a word puzzle made of paper: typewritten labels, washi tape and tiles that look cut out by hand. There are no timers and no lives. Try as many moves as you like. HOW IT PLAYS • Each board has 40 words in 8 rows, and every group of five words shares something. • Drag a tile onto another to swap them, or tap one tile and then the other. • Get all five right and the row is taped down, with its group written above. Solve rows back to back for a streak bonus. • Solve a board without help for three stars. 140 LEVELS AND A DAILY PUZZLE • 140 hand-made levels, each marked easy, medium or hard. • A new daily puzzle every day, with a streak to keep and an emoji grid to share. HELP WHEN YOU'RE STUCK • An Inkling links two words from the same group. A Clue names three groups. • Pick up a tile first to aim either one at that word. • Hold a tile to look its word up in the dictionary. • Up to three unsolved levels are open at once, and each keeps your board, so one hard level never holds you up. • Still stuck? Spend stamps to have a row solved for you. MAKE IT YOURS • Earn stamps as you play and spend them in the shop: tape colours, tile papers, row seals, desks, confetti and sound packs. • Eight sound packs, from rustling paper to a music box. Every row you solve plays a note higher than the last. • No in-app purchases. Everything in the shop is earned by playing. PLAYS WITH VOICEOVER • Double-tap two cards to swap them, or move a card up or down a row from the Actions rotor. • Hear each row as you solve it, and two-finger double-tap to hear the words that are left. ANY SCREEN, ANY WAY UP • Play on iPhone or iPad, upright or on its side. • Made for iPhone Duo: play folded on the outer screen, or open it up for a bigger board. NO ADS, NO ACCOUNTS • No ads, no tracking and no sign-in. Word Tack works fully offline.
