A free 2 player marble game

Two players sit at opposite corners of one phone or tablet and flick at the same time. A round takes a minute, so "best of 5" comes naturally.

Best modes for two players

Turn-based, five marbles each, with a 100 point centre.

The head-to-head race for holes.

Hold the moving zone longer than your opponent.

A straight duel: knock theirs off, keep yours on.

With two players the corners used are opposite each other, so you face your opponent across the screen.
A phone is big enough for two. Turn it sideways and put it flat on the table.
Set Match to Best of 3 or Best of 5 and the game keeps the tally and shows a trophy at the end.
If one player is much younger, they can tap their score to switch on Easy help for their corner only.

Yes. Two players take opposite corners of the same screen and play at the same time. A phone held sideways and laid flat is large enough.

Hole in One if you like taking turns, Classic for a fast head-to-head, and Last Marble Standing for a duel.

Yes. The child can tap their score to turn on Easy help, which makes their targets more forgiving without changing anything for the adult.
