A stone does not care how it was meant to be moved. Joker Royal Coins is a bench for working out what a monolith actually costs to shift: gauge it in your own photograph, set the rock, then lay the road leg by leg until the thing stands in its socket.
For the dig director sizing a lift: photograph the block or the disc dead-on, drag β a two-pin rod onto a feature of known length, then drop the face pins. Length, width and height fall out of the scale, volume follows the form β block, disc, stela slab, column drum, lintel, step tread β and one of eight rocks turns that volume into a mass at its published density.
For the experimental archaeologist laying a route π§: every leg carries a method β timber sledge, log π rollers, greased skid, corduroy track, shear legs, lever and crib, anchor post β together with a ground, a track state and a gradient. Joker Royal Coins returns tractive force, the pull on each hauler, the crew, roller spacing, bearing pressure on the ground, rope tension against the working load and the day's run, and closes each leg on HOLDS, MARGINAL or OVER with the margin in kgf and what to change.
For the student asking how it stood up: the last leg is the raising. Add crib courses, set the lever throw and the tilt angle, and Joker Royal Coins draws the stone rotating up onto the socket edge with its centre of mass tracked and the tipping point marked β overturning moment against restoring moment, and the crew it takes at the bar.
For anyone reading about a move that already happened: twelve dockets arrive loaded with real monuments and their published dimensions, so the figures Joker Royal Coins works out can sit beside the ones the literature gives.
Units, the pull you credit each hauler with, the safety margin and the rope standard are all yours to set, and every figure on every screen follows them. Everything is worked out on your device π±, and the app needs no connection to do it.
A planning and teaching bench, built on published rock densities and standard friction ranges. It is not an engineering lifting authority and does not pretend to be.
Work out how a carved monolith moves, and whether it stands up.
