Your own chips: after level 6, turn the circuit you built there into a chip for the Logic Lab. Later, the full adder, ALU slice and other parts you build take the place of the standard parts in the levels that follow, once they pass a full check. You can switch back to the standard part at any time. Saved works: each level you solve, from level 1, keeps your circuit. View your wiring, give it a name, or copy it to the Logic Lab. Sign your works and chips; share codes can carry your signature, and you can remove it before sharing. Parts collection: a new section next to Achievements, with a card for every part. Flip a card for its truth table or an example. Cards tilt as you move your device. Fix: you can now take a single bit of a number (choose it when you drop the wire) and wire bits one at a time into a display. Level 14 and several later levels could not be finished before. Also: running circuits redraw only what changes, and game sounds and ambience come back after a call or when you return to the app.
