Open Osmium

Goal

Move all cards to the foundations.

At a glance

Just like Osmium, but the rows are dealt face-up, and the remainder of the deck is dealt out face-up as reserve cards that can be moved to the foundations at any time.

Like Open Peek, but with Osmium rules.

Base game rules: Osmium

Goal

Move all cards to the foundations.

At a glance

Just like Osmosis, but all four foundations must be built in the same sequence of ranks. Additionally, the order of the foundations doesn't matter and cards are dealt one at a time from the stock.

Base game rules: Osmosis

Goal

Move all cards to the foundations.

How to play

A single card is dealt to the first foundation, and four cards are dealt to each of four tableau rows, with only the top card visible. No building in this tableau is allowed. The remaining cards are dealt three at a time from the stock. On this first foundation, any card of the same suit as the first card can be played.

Lower foundations are started with a card of the same rank as the first card. Subsequent cards played to these foundations must be the same suit as that first card played to it, and have a rank that matches that of a card that's already been played to the foundation directly above it.

The game is won if all cards are moved to the foundations.
