Rings turn one notch per tap. A dot can hop to the next ring only at the exact moment two rings kiss. Land every dot in its socket in the fewest moves. A logic puzzle with one exact rule, no timer and no luck. NEW IN 2.0: ENDLESS A fresh board every time, made on your phone and proved by the solver before you see it. Six difficulties, drawn at random after an easy start, from gentler than Orbit 1 to as tough as Orbit 6. Solve at par to grow your chain. No timer, no lives, no end. ONE RULE, EXACT Tap anywhere and every ring clicks round by its own spin: +1, −1, +2, or not at all. Tap a dot while it sits at a kiss and it arcs across to the touching ring. That is the whole game. Nothing is random inside a level and nothing is timed, so every board is a small piece of clockwork you can read before you touch it. THE CLICK OF GEARS MESHING The feeling you chase is the socket swinging into the kiss as the dot arrives. Every tick, hop and dock has its own sound, haptic and light: the notch marks blink in sequence, the hop leaves a luminous trail, the socket blooms, and a solved level ends on one calm chord. 120 LEVELS IN SIX ORBITS Every level was generated and proved by a solver, so par is the true minimum and a level is never unsolvable, only over par. Every orbit is free to reach: earn 40 stars in one and the next opens. Each adds one twist: • Kiss – two rings, one dot, one socket. Learn the hop. • Wall – a stop bar rides the ring and refuses a landing. • Flip – a marked notch sends its ring the other way. • Three – a third dot, and three colors to route at once. • Still – rings that do not turn, and mixed spins. • Tangent – everything, on twelve-notch rings. Three stars means par. Undo is free and unlimited, restart is free, and one hint per level shows the solver’s next move. ONE DAILY, ONE STREAK A new brain teaser every day, built on your phone from the date, the same for everyone. Par is shown before you start. Solve it and your streak grows; share the result as text, not a screenshot. Reminders are optional, up to three a day, and stop once the day’s puzzle is solved. MADE TO BE READ Every dot and socket carries a shape as well as a color, so no rule depends on color alone. Reduce Motion turns every pulse and burst into a fade. VoiceOver and Dynamic Type are supported throughout. Sessions are two to five minutes, one-handed, and every move is saved, so you can put the phone down mid-level and pick up exactly where you were. WHAT’S INCLUDED • Game Center: leaderboards for total stars and best streak, seven achievements. • iCloud: your progress follows you to a new phone. • No account, no in-app currency, no lives, no timers. FREE TO PLAY, ONE UNLOCK TANGENT is free to play, with ads: a banner on the menu screens, never on the board, and now and then a short ad between puzzles. TANGENT Full Game ($4.99, once, no subscription) removes every ad, opens all six orbits at once, and adds the daily archive of the past 30 days and Skip board in Endless. Without it, you can watch an ad to skip an Endless board. Restore Purchases and offer-code redemption are on the Unlock screen and in Settings.

Verdict
The clearest difference is rating: TANGENT at 5.0 against Alien Attack's 3.8. Alien Attack's advantage is in-app purchases (none vs 1) and update cadence (daily vs every 3 weeks). On price and ads there is nothing between them.
