Open valves to dose exact percentages of coolant into a string of miniature reservoirs. Play 24 levels in each of three difficulties. The 3D playfield supports touch and mouse, with keyboard controls and optional sound.
How to Play Meltspan
Read each reservoir’s capacity and target percentage. Work out the target volume, then tap the plus or minus valves. Lock the dose when the volume is right. Hard stages use a primed reservoir and finer percentages. Choose Easy, Medium or Hard, then pick a level. Clear a stage to move on, or use the restart button to replay it.
