Train your brain with scientifically-backed games. Each exercise is designed to strengthen memory, attention, and cognitive skills based on 50+ years of research.
Explore Games ↓Testing Effect (Roediger & Karpicke, 2006): Active retrieval is 50-80% more effective than passive reading. Each flip = a test trial that strengthens neural pathways.
Dual Coding Theory (Paivio, 1971): Combines verbal (words) + visual (placement) = double encoding = 2-3× better recall.
Spaced Repetition: The algorithm adjusts intervals based on performance, providing 200-300% better retention than massed practice.
Activates hippocampus (episodic memory), prefrontal cortex (executive function), and parietal cortex (visuospatial processing). Repeated activation strengthens synaptic connections via neuroplasticity.
Executive Function Training: GO/NO-GO paradigm (Aron et al., 2014) trains inhibitory control via right inferior frontal gyrus. Critical for impulse control and attention.
Sequence Learning: Activates hippocampus CA1 for temporal binding. Strengthens synaptic plasticity via LTP (Karlsson & Frank, 2009).
N-Back (Jaeggi et al., 2008): Training improves fluid intelligence (gF). Activates bilateral DLPFC + posterior parietal cortex.
Studies show generalization to real-world tasks: better multitasking, improved decision-making, and increased cognitive reserve.
Generation Effect (Wittrock, 1974): Self-created content = deeper processing. Effect size d = 0.71 (large effect). You learn 3-4× better when YOU create the material.
Picture Superiority Effect (Nelson et al., 1976): Images are remembered 2-3× better than words. Dual encoding via visual + verbal system.
Production Effect (MacLeod et al., 2010): Self-produced audio → +15-20% better recall. Activates Broca's area.
Combinations of media create rich memory traces with multiple retrieval cues. Research shows +40-60% better retention vs. text-only.
Personalization (Bloom, 1984): 1-on-1 tutoring = 2σ improvement. AI provides personalization at scale with 98% relevance vs. ~40% in generic material.
Cognitive Load Optimization (Sweller, 1988): AI filters irrelevant info and structures content logically = more mental capacity for actual learning.
Difficulty Calibration: Level 1-3 matches expertise. Beginners get scaffolding, experts get nuances.
Semantic coherence, consistent difficulty mapping, cognitive diversity, and knowledge integration from etymological databases + linguistic knowledge.
Testing Effect: Each flip = retrieval practice. Immediate feedback strengthens correction signal.
Automaticity (Schneider & Shiffrin, 1977): Speed mode drives transition from controlled (effortful) to automatic (effortless) processing. Frees cognitive resources.
Multi-modal memory: Images, sound, and video create multiple retrieval cues and stronger encoding.
Start with Normal Mode for encoding → Switch to Speed Mode for consolidation → Achieve automaticity. Research shows 2-3× better retention than traditional methods.
Spreading Activation (Collins & Loftus, 1975): Thematic structure = semantic networks. Related words activate each other → stronger associations.
Elaborative Encoding: Etymology modals provide deeper processing. Effect: +40-60% better retention than surface-level learning.
Contextual Learning: Themed content > random words. Schema integration improves both encoding and retrieval.
Level 1-7 (2×2 to 7×7) provides progressive challenge. Adaptive difficulty keeps you in flow state (Csikszentmihalyi, 1990) = optimal learning.
Formative Assessment (Black & Wiliam, 1998): Feedback effect size d = 0.7 (large effect). Real-time data provides actionable insights → targeted improvement.
Metacognition (Flavell, 1979): Awareness of learning patterns → better study strategies. Dashboard shows which pairs are hardest → deliberate practice.
Growth Mindset (Dweck, 2006): Visible progression motivates continued effort. Curves show improvement over time.
Reaction time, accuracy, streak count, session stats, per-pair performance, learning curves, and long-term retention. All data is used to personalize your learning.
Personalization (Bloom, 1984): Learning about topics you're interested in = 2-3× better retention. When parents create games about subjects their children care about, engagement increases dramatically.
Zone of Proximal Development (Vygotsky, 1978): Three education levels ensure content matches developmental stage. Elementary = concrete thinking, Middle = abstract concepts emerge, High School = formal operations.
Topic-Based Learning: Why-How questions activate causal reasoning (prefrontal cortex). Scientific Methods train critical thinking (DLPFC). Ecosystem Interactions build systems thinking (parietal-temporal networks).
Adaptive Difficulty (Vygotsky, 1978): Three difficulty levels ensure optimal challenge. Too easy = boredom, too hard = frustration. Balanced difficulty = flow state = optimal learning (Csikszentmihalyi, 1990).
Parents can create games about dinosaurs, space, cooking, or any topic their child loves. Students can explore their interests - from marine biology to rocket science. Teachers can create curriculum-aligned games. The AI Theme Generator lets you input any subject and automatically generates educational content with definitions, etymology, and mnemonics. Research shows personalized, interest-driven learning improves motivation by 40-60% and retention by 30-50% compared to generic content.
