Tiamat turns cellular automata into a creative, relaxing sandbox for patterns, rules, colors, and discovery. Build living worlds from simple rules, then watch order, chaos, gliders, oscillators, and unexpected structures emerge. Start with familiar Game of Life-style behavior, import or export rulestrings, tune simulation speed, paint directly on the field, and save the fields, rules, gradients, and patterns you want to revisit. What you can do in Tiamat: - Explore Conway-like cellular automata with wrapped, borderless fields. - Create, edit, save, import, and share rules with BS, SB, and HROT rulestring support. - Paint cells by hand, place saved patterns, or generate random fields. - Customize gradients and fading to make simulations easier to read and more beautiful to watch. - Save favorite worlds, layers, rules, colors, and patterns for later experiments. - Learn cellular automata concepts with built-in help and changelog articles. Whether you are studying emergent systems, looking for generative art inspiration, or just want a calm mathematical sandbox, Tiamat gives you precise controls without getting in the way.

Verdict
The clearest difference is in-app purchases: Orbitals at none against Tiamat's 6. Orbitals also leads on iOS requirement (15.2 vs 26.0). On price, ads and device support there is nothing between them.
