A museum shop now stands by the tunnel arch, and opens once you have your first exhibit. Spend the kudos your visitors pay on upgrades for the museum, your plinths and yourself.

Five boosts, each for one round: Slider soles, Fleet foot, Steady hands, Head start and Lucky pockets. They cost more the deeper the museum digs.

The closing bell is now bought at the shop, and once bought it stays in every museum you open.

The boosts you bought are shown in the corner of the screen during the round, and light up when they help you. Slides kick up dust, running leaves wisps at your ankles, extra taps glint, and lucky finds flash gold as you pocket them.

Plinth enhancements: give a piece's plinth a finer stand, then gallery lighting, then a stand made for it, so it draws more visitors. The Seer's Eye and the Rosewood Casket have theirs; more are coming.

Rare finds: nine unique antiquities hide in the mounds, given away by a rainbow glint. Bring them home to keep, along with your first pottery shard, bead and coin.

Display cabinets: buy up to four and your kept finds fill them on their own, behind the plinths, for more visitors.
