Description
✦ Stellarum — Cosmic Rummy ✦
13-card Indian Rummy, dealt among the stars. Cards are stars, sequences are constellations, a declaration is a Grand Alignment — but the rules are the rummy you already know.
■ Every opponent is an AI
This is not a real-time multiplayer game. Everyone at the table is an AI. Conquest and Defense point at other players' stars, but what you actually face is the AI they left on guard.
■ The rummy core
· Two decks plus jokers, 13 cards each · Every deal picks a wild rank — those cards and the printed jokers fill the gaps in your melds · A win = two sequences (at least one pure) with every remaining card in a valid meld · Arrange and group — drag your hand, bind melds, unbind them, sort it your own way · AI Coach — one line of advice on what to draw and what to discard (switch it off any time) · Four difficulties — Easy · Normal · Hard · Expert
■ Three modes
· Rush — a four-player table. Finish first to climb floors; a boss floor closes every sector · Conquest — take on three rivals near your own star level · Defense — post your AI in front of your mining tunnel and it holds the line while you are away
■ Grow your star
Collect Stardust at the mine, widen your star's diameter, fill out achievements, and leave your mark on the lifetime, weekly and daily boards. Star Energy refills on its own over time.
■ Offline too
Lost your connection? Practice rounds against the AI keep running.
■ About in-game items
Stardust (SD) and Star Energy (SE) are in-game progression items only. They cannot be exchanged for anything outside the game, and no real-world currency is involved.
