The iOS version of Entanglement features four game boards, the classic board plus three new boards exclusive to the iOS version. It also features a new mode, Gold Rush, which adds a twist to the traditional Entanglement by introducing golden paths to the mix. Cross a golden path to uncover a gold nugget. Earn points for each tile the nugget crosses returning to the mine cart. Note that contrary to the locked button in-game, the iOS version of Entanglement will not be updated with a mode in addition to the two already in place.
