Three flasks, a finite supply of elixir and one exact formula. Choose a source, then a destination. A full pour stops when the source empties or the destination fills. Reach every visible target amount before the move budget runs out.
Eighteen formulas use different flask capacities and complete conserving solutions. The brass meter can spend a charge on a chosen exact transfer. The reservoir valve returns liquid to the actual tank or refills a selected flask from what remains there. Every valid pour or valve operation uses a move; empty and impossible actions spend nothing.
Watch translucent liquid settle inside the glassware as the formula takes shape. One undo voucher restores the previous volumes and measuring charge, while Retry starts the current formula afresh. Revisit chapters freely and track the formulas you have completed.
Pour conserved elixir between flasks to make eighteen exact formulas.
