Trace
Read full descriptionHide full description
Trace is a minimalist brain puzzle game about memory and steady hands. Each level briefly reveals a maze — walls or a glowing path — and then it's gone. Now retrace the route from start to finish in one continuous gesture. From memory. No timer on the solve phase. You don't have to be fast. You have to remember, and trust what you remember. BRAIN TRAINING Trace works as a daily exercise for short-term memory, spatial reasoning, and focused attention. A few seconds to absorb the maze, then it's just you and the trace you draw from memory. Short sessions, real cognitive load — five to ten minutes a day adds up. CORE MECHANIC • Memorize the maze in 3–8 seconds • Draw the solution in one unbroken motion • Fail, retry — but tougher levels don't fully reset CHECKPOINT FLAGS Before each attempt you can plant a flag mid-path. If your stroke reaches the flag but fails later, that section banks — next try starts already-completed up to the flag. The game rewards careful play, not frantic retries. FOUR CHAPTERS • Spark — tutorial, simple paths • Echo — 3×3 and 4×4 walls • Dusk — start and finish hidden during memorization • Abyss — 5×5+ grids, sometimes rotated between memorize and draw WHAT IT TRAINS • Short-term memory — hold the path in mind after a brief reveal • Spatial reasoning — a route, not a picture • Concentration — one steady gesture demands certainty • Attention to detail — every cell matters LOOK Clean geometry, calm palette, nothing extra on screen. Dark and light themes — switch manually or follow system. WHO IT'S FOR For people who like puzzles calibrated to demand attention, not reflexes. Calm focus, not speed. Made for the 5–15 minutes between things — and effective as a regular memory workout. svyatoslavdp@gmail.com

Sumloom — компактная головоломка о числах, цепочках и петлях. Выберите один из трёх коротких заказов и проведите пальцем через соседние плитки с числами 2, 4, 6 и 8. Соберите точную сумму, чтобы выполнить заказ. Замкните линию в петлю, захватите клетки внутри и удвойте награду. Обычная игра не ограничена партиями: каждые 10 заказов начинается новый уровень. Выполняйте заказы подряд, увеличивайте множитель серии и улучшайте рекорд столько, сколько захотите. В игре есть: • понятное управление одним пальцем; • три доступных заказа одновременно; • небольшие чётные числа без сложных вычислений; • бесконечные уровни и бонусы за серии; • удвоенная награда за замкнутые петли; • бусты «Обновить», «Обмен» и «Отмена»; • интерактивное обучение прямо на игровом поле; • ежедневное испытание, одинаковое для выбранной даты; • локальные достижения, статистика и цветовые темы; • звук, вибрация и настраиваемая интенсивность эффектов; • автоматическое сохранение бесконечной игры; • полноценная работа без регистрации, рекламы и интернета. Играйте короткими сессиями или улучшайте рекорд столько, сколько захотите. Все игровые данные остаются на вашем iPhone.

Verdict
The clearest difference is ads: Sumloom at none against Trace's shown. Sumloom also leads on update cadence (every 2 days vs weekly). Trace's advantage is device support (3 vs 1) and iOS requirement (14.0 vs 17.0). On price and in-app purchases there is nothing between them.
