TIDELINE

A calm puzzle about steering colored light, for iPhone.

How it plays

Beams of colored light cross a small board. Tap mirrors, splitters, prisms, and combiners to turn them, and drag pieces from the tray onto the board, until every receiver glows in exactly its color. There are no timers. After the first chapter, each level gives you a budget of moves; run out and you lose one of five lives, which come back one every twenty minutes. The campaign has 120 levels across eight chapters, with more in chapter packs (Deep Water, and from version 1.1 The Reef and The Ice Coast), and Daily Light gives everyone the same new puzzle every day.

Pearls, videos, and the shop

Pearls are earned by playing and pay for undos, hints, extra moves, and lives. From version 1.1 a tide chest washes up every day, and if you like, you can watch a short video for a free hint, a life, more moves, or double Pearls, but only when you tap an offer: there are no banners and no ads that interrupt play, and the Daily Light never has any. The Keeper's Pass gives unlimited lives and every video reward without the video. Today's Daily Light is always free and the same for everyone.
