Assimilax

Assimilax is a game of quiet conquest: spread your colour across a hex board, one pastel orb at a time, until everything on it is yours. Each turn you do exactly one thing. Pick an orb and either CLONE it to a neighbouring hex (the original stays) or JUMP it two hexes across the board (it moves). Either way, every enemy orb touching where you land is ASSIMILATED — quietly flipped to your colour. That's the whole game. No timers rushing you, no menus to wade through — just you, a hex grid, and a slow, satisfying tide of colour spreading across it. Under the soft palette is a real strategy game: • 40 hand-built levels and a gentle tutorial, laid out as concentric rings on a hex map. Start at the centre and climb outward. • 3 boss battles gate the rings. • 6 playable orbs, each with a special power that charges as you play: Coral's Embrace, Azure's Flow, Sage's Root, Honey's Glow, Lavender's Drift and Stone's Anchor. Time one right and the whole board tips your way. • Three difficulties. Easy plays loose and forgiving; Normal keeps you honest; Hard thinks a move ahead and never blinks. Lives and continues soften the fall — or don't, on Hard. • A global leaderboard — leave your three letters at the top. Everything is tuned for calm: soft pastels, a chill soundtrack, unhurried animations. Pick it up for one quick level, or lose an evening climbing the rings. No ads. No in-app purchases. No account. Works offline. Just a board to take, one orb at a time.

Verdict
The clearest difference is ads: Assimilax at none against Shogi 4×4's shown. Shogi 4×4's advantage is iOS requirement (13.0 vs 15.1). On price, in-app purchases and device support there is nothing between them.
